P: Extensive masking on iPad Pro resets settings and looses the edits
Issue: Extensive refining of a mask using the brush tool seems to reset the settings and loose the masks altogether.
- Lightroom version: 7.01
- OS: IPad Pro 12.9 5th gen, Ios 14.8, 2 TB with 1.78 TB free space
Steps to reproduce: Prior to upgrade to LR Mobile ver 7, Import Canon CR2 Raw file into IPad Pro. Make basic color and exposure changes. Working with full resolution file. (Canon Eos5dmkIV).
1. Create mask using the auto sky mask, the create mask using auto subject (initated in
Lightroom Classic for desktop and sync'd via cloud)
2. Choose to create a subtraction mask using brush. Erase mask areas that spill over from
the subject to the background and leave the red preview on. For example, an outdoor portait shoot.
3. After several minutes of brushing, the brush no longer erases the mask. All color and exposure edits seems to revert back to the original file or last session.
4. Return to Adobe Classic, developer module, history, undo 'reset setting' to restore color
and exposure edit prior to the masking session. The Initial AI mask may be retained, but the brush edits are still lost.
5. Assuming this was an out of memory issue, I went into all the open apps and forced quite a 2-3 dozen or so apps, leaving open a handful of apps. Repeated the masking and the bug repeated.
6. An iPad reboot has not been explored.
Expected result: mask refinement (adding or subtracting mask pixels)
Actual result: Lightroom mask brush stops working, the file seems to revert to an very early history state if not the original import.
