Pictures dont sync to Lightroom CC Mobile

I removed one picture from catelog marked as pending, LR had an problem with that picture, it was old so no problem deleting it. But after that I checked the sync log again, but that pictures is still in cloud and still showing up as pending in the sync log..

Would the pending ones stop the others marked as uploading in the sync log?

Except if you are on a fast fiber optic connection, you probably only have about 5 megabit/s of upload speed. Most cable and DSL networks are extremely asymmetric with the advertised speeds only applying to the download and not the upload speed and a factor of 30 difference is not uncommon.

If you are syncing full RAF files LR first has to create a Smart Preview of it then Upload that smart preview to the Web system and then down load it to the mobile version of LR CC. All of that takes time.

And depending on the Upload Speed of your internet connection it can take a Long Time.

Open the LR Preferences and go to the Lightroom Sync tab and then look at the Sync Activity section. Are there any errors.

If there are you can hold down the Alt key and 2 buttons will appear, Generate Diagnostic Log and Rebuild Sync Data. you can try the second to rebuild the sync data.

Have you checked the Activity center to ensure that syncing isn't paused? Click on the white triangle to the right of your name at the top leftmost part of Lightroom. The file type shouldn't have any bearing on syncing from a collection.
