Yes, I use the v6.22.0 Pro version from the Play Store.
In 6.23.0 it was removed: https://github.com/SimpleMobileTools/Simple-Gallery/releases...
But in 6.23.6 it should be there again: https://github.com/SimpleMobileTools/Simple-Gallery/releases...
But it seems it won't happen for the Play-Store version: https://www.reddit.com/r/SimpleMobileTools/comments/uqqqsj/c...
