Having spent many hours creating and refining my IOS mobile app, I am disappointed to apparently see that my most recent tab (there are 5 tabs in my app) has somehow disappeared! And in the process it renamed the next tab to the right with the name of the now deleted tab. This seemed to happen when I added the 5th tab to the app…is there some limitation to the number of tabs (I am PRO Plan) that somehow deletes from the left a tab if a new one is added? This is really frustrating as I don’t see a way to recover. Do I need to somehow back up my work to avoid this in the future? Thanks
