Plus one for me, too. Only use an iPad 11” pro for all my work as an Office Manager, and the only thing I can’t do/use is QBOnline. It’s extremely frustrating. Been a QuickBooks customer since 1994! Same issues as mentioned by others, scrolling, no “Save & Close” button selection, etc. Tried Firefox, Chrome, Safari. Will have to switch to another accounting option, if Safari on IOS 13 doesn’t fix this, since QBooks doesn’t seem to want to.
