Using beta 2.22.9 on iOS 11.2 on iPhone 6+
App is stable. No crashes.
Navigation buttons disappear which is annoying because “add set” also disappears. This seems to happen when a break and set take a little longer. Maybe around 2 minutes.
Exercise names disappear after reaching the 5th exercise. Going back into the exercise screen as if I were adding another set brings the name back on the main screen.
I added a seventh exercise without recovering the name in the 5th and 6th exercise thinking that maybe they would come back on their own, but they stayed blank.
Overall I still love the app.
