Is this happening solely on the iPad?
I was looking at this and wondered if it was related. Lightroom mobile tells you you're using trial version
Have you tried quitting the apps on the iPad, Double press the button on the front of the iPad to where you get all open apps shown as windows horizontally, find the Adobe apps and do a flick gesture upwards to close them or you can completely power down the iPad to where you get the Apple logo when you restart.
Tried any of these things?
