P: Extensive masking on iPad Pro resets settings and looses the edits

Disregard my previous comment about syncing issues, apparently auto update was out of whack and my version of Lightroom CC was out of date.  Newbie problem solved, nothing to see here, move along.  (I couldn't find a way to delete my previous comment, is there one?  Sorry!)

I'm having a seemingly related problem but with a couple of distinctions: I edit photos on my phone with Lightroom ios, including mask/selective edits and others like light or crop, and all edits sync to Lightroom CC on my laptop and Lightroom iPad EXCEPT the mask/selective edits, but the edits remain in effect on the phone unless I subsequently make a mask/selective edit on another device and then the phone syncs to THOSE edits.  I did some basic editing to about a dozen photos on my phone while on the train this morning and discovered this when I went to fine tune the photos on a larger screen, and with half a day gone by now with all devices online now the mask/selective edits are still the ONLY thing that hasn't synced, but they're still there on the phone copy for now.

Good to know!  I decided to follow your advice and try working on the problem photo again. In fact, the masking stopped applying the brush strokes after a minute of work. This is consistant as before, only it occurred faster. I chose to wait 20 minutes, with a periodic brush stroke within the first 10 minutes, without success. Now, just for clarity, this bug doesn't have a lag like other memory issues I have experienced. The action simply stops. I can hit 'Done' on the edits. When I switch photos and return, the masks are deleted as before. Something new: The preview seemed to take a while on both photos and all I had was a black screen for 2 to 3 minutes. Also note: I did have LRC open on my desktop while my computer was asleep for the night. There was a different photo that was in focus.

@Ecphotographer 

concerning the memory handling on iOS/iPadOS, what at least used to help was to kill all apps manually and then doing a reboot of the device.
That would make sure that those apps don't start automatically on startup again AND that any system memory issues that might have occurred have been reset.

Please let us know if that helps.

Thanks,

Thanks! I never saw the LrD pull down filter until I saw your screenshot (only the syncing tag).  Any thoughts about this discrepancy? (see attached). The corner icon shows ync is in progress, but the filter shows no files.

Hi Ecphotographer, to "re-inforce" sync, you could select Cloud icon (top right) on iPad and then Pause/Resume Syncing. The same in LrClassic, under the Cloud icon, or re-launch the apps.

To check sync status in LrD, use Filter > Sync Status (on top bar).

Hi Elmira,

I never executed the reset settings tool button. After I refined my mask in Ipad LRmobile, and where it seems to hang and loose the edits, I return to LrClassic (LRC) to use the history tool to revert back to the global edits prior to masing. The last history state 'Reset Settings' is indicated and I choose to select the history state prior, which has my global color and exposure edits. As in my last post, I haven't been able to reproduce the error on other files. Thus far, its just one in particular file with at least 23 actions performed in LRC prior to moving to Ipad LRmobile. What I haven't done yet, is to do 23 or more edits in LRC and then sync Ipad LR Mobile.  I think small mask edits on the Ipad are ok, its lenghtly edits on the Ipad that eventually quit. Its either a memory problem or a sync problem...  Is there a best practice in working with the Ipad's memory restrictions?

Thank you everyone for your consideration in this matter. I've narrowed down the possibility of the bug to just one file. I am thinking perhaps, I need repeat the steps (using LRC history) to a new file and see if there is a specific sequence to the bug. First, do global edits in Ipad mobile, Then use the AI filters in LRC, use additional and subtraction masks within LRC, then move to Ipad LRmobile for refinement. Otherwise, refining the masks in Ipad LRMobile seems to work normally.

Now, is there a best practices / don't do's list with regards to the cloud sync? I experience and instincts tell me its related. I do work with LRC, drag my sync hi-res files to LR to sync up to my Ipad LRmobile. I've noticed large PSD (250mb files or greater) seem to hang up in the sync. I sometime leave these apps open on my desktop for hours. Is there a recommend sequence to syncing with the cloud, beyond the obvious? That is to say, sync first with LR before working in LRC?

Getting back to this problem, I edited another photo in Ipad LR Mobile from the batch and I can't get the new mask edits to sync to LRC. I edited the metadata to 'trip' the sync. For ex. I added a blurb in the Title field, no luck, then created a brush stroke in Ipad LRmobile, but the masks edits aren't updating in LRC. I dare not make any adjustments in LRC until the sync is correct. Is there way to push updates?  Thank you in advance, E
