out of curiosity are you dealing with hosted files from FMS, or local files on the iPad?
sorry - forgot that: Only local files!
I installed my 'checker scripts' - and every test script runs not bad, but the spinning wheel appears really more often.. and it was NOT a problem under iOS8.
I had to download that fike on my Mac and upload again after changes. The first few tests were faster, then the spinning wheel appeared again
I've been doing some testing myself but haven't seen the behaviors you're describing in my local files. Some of the remote ones though on slower connections (coffeehouse wifi and LTE) has been noticeable, but nothing too different than iOS8+13/14
I've been testing on an iPad mini 2nd gen.
as I wrote the answer to TS Pigeons post, the keyboard did not pop up - in jive... second time today
I'm doing really a lot with my iPad (Air2), all day long - and it's getting really worse under iOS9. While answering this posting, I can't move the cursor using my finger, again... (a long tap will not move the insertion mark - but this can be jive..)
I find the button bar with the formatting tools bad, really not needed here - I hit underline etc one or another time accidentally - but this is ok (I know why happens..)
but I strongly believe in Steve Jobs reasoning: A touch devise is a touch device, not something with keyboard, mouse, pen, etc...
when one uses the ipad on the road (means trains, busses,), often one writes with one or two fingers... adding unnecessary buttons will break that use-case. The new split view breaks the one-finger swipe in the browser... swiping back works, swiping forwards will bring up split view...
FIleMaker is just one thing - but I encountered problems on several devices in several apps - and jive is still one of the worse ones concerning iOS.. What also happens: Text will disappear under new button bar (formatting bar)..
