Vignette cannot be applied AFTER "Modern 3" profile is applied in Lightroom Mobile on Android. If vignette is applied beforehand it works fine but it cannot be changed after. I tried many other profiles, "Modern" and others, and didn't run into this. They worked fine. I use this one often and has been going on for awhile. I usually end up putting a radial filter on to bypass this issue.My current device, an LG G7 w/ Android 9. Also happened before upgrade when it still was Android 8. This also happens on my LG G Tab X 8.0 (LG-V521) tablet w/ Android 7.0.I have not tried this on a PC version of Lightroom CC or Lightroom Classic to see if the results were the same.
