Swipe to highlight doesn’t work in the current beta (25.0.0.0039) on iOS. It appear to initially work when I start to swipe, but the highlight never appears. If I do a text selection first, then apply a highlight to that selection, then I can get a highlight, but swipe to highlight still fails. The app is also not remembering the last used highlight styles. If I reinstall the released version then both these things work correctly.
I also reported this through the app, but I thought I post it here too in case anyone else has the problem.
