This has worked fine for both auto-mobile uploads and manual uploads. For whatever reason though it has stopped working. On import images have names like "IMG_0014.JPG:" not including my custom setting. Attached are some screenshots. What gives?
What do you mean with "Auto Mobile uploads"? Renaming images should work on import, but not if you sync down images from the mobile app.
Sorry, I just mean when my mobile uploads sync with Lightroom Classic (ie not plugging in a memory card and manually uploading). What I mean is none of my uploads inherit the defined custom Rename File that I have defined. They all have names like "IMG_0014.JPG:". Imbedding images here.
I don’t think automatic file renaming has ever applied to images synced down to Lightroom Classic. Although you showed your custom File Renaming panel settings, those are in the Import dialog box…but the Import dialog box applies only to files coming in during a current one-time import from a local file system, such as a camera card or hard drive. Files imported through the online sync process do not go through the Import dialog box, so files imported by sync are not going to use those File Renaming settings or anything else in the Import dialog box. The only customization you get for files synced down is their destination folder, which is set in Preferences, Lightroom Sync tab, Location section.
I have to keep a Smart Collection that looks for filenames that do not match my custom setting. As images sync down from my phone and tablet, that Smart Collection grows, so every once in a while I select everything in the Smart Collection and press F2 (the shortcut for Library > Rename Photo) so I can rename them all with my standard file name preset.
