I have an iPad Pro 10.5 and the same problem - somtimes. Only today, 31 DEC 17, I opened a NEWS APP and when I clicked on a story the page that came up was ‘white’ - nothing else on the screen but white. I could not get rid of it with any kind of tapping. Closed the APP and when I double clicked the HOME button I could swipe the page off and went back into the APP and comntinued reading NEWS. But when I clicked on that one article that white page came up again. Went through the same process and recovered. So, I then went to TELEGRAM, did an update and saw the new wallpapers. Then I checked out the new wallpapers and when I clicked on one of the wallpapers it popped up and froze and would not let me do anything in the APP. I then did the same HOME button, double click and swipe off. Went back to the APP and it works fine - unless I touch that background thing. OK, that may be the APP and I’ve written TELEGRAM about it. So far the screen has not frozen again when reading online. Hope that was just a fluck and it doesn’t happen again.
My wife’s iPad Pro 12.5 G2 is working fine.......so far. Actually the 12.5 G2 is an really nice device.
A few other things really confuses/bother me though. Like now, I’m using a Magic Keyboard ⌨ to write this reply. While all works as normal if I use an arrow key, to scroll up or down, the whole page moves to the very bottom of the web page but if I hold the arrow key down it does move within the text - I just can’t see it until I go back up to the page I’m writing on. Strange.
Looking forward to more comments as this delima unravels.
