Unfortunately there are multiple bugs with the 5.90 iPad app, some of which are not subtle.
Perhaps most problematic is that search results display "too high" up the screen, so that sometimes only the bottom few pixels of the results display below that tab bar showing Shows, Movies, Episodes, etc; sometimes not even those few pixels so that it looks like no matches are available.
Second (seems trivial, but is endlessly irritating) is that moving away from any of the "deeper" screens in Guide reverts you to the top of Guide. For example, suppose I go to Guide, then tap the button in the upper right to get On Later, then tap the More> of On Tonight. If I then move away from the list of On Tonight, either within the app (by tapping Search) or outside the app (by context switching to say IMDB) when I return to Guide I will have been bounced back up to the "front page" of Guide, ie the list of channels and times.
Third there appears to be a memory leak in the display of posters, especially associated with pages that can show many posters like the On Tonight or Upcoming Movies full pages. Symptoms are that we move from all the posters being shown correctly to half the poster slots are blank, half show a poster, to a minute or so later the app crashes. This is absolutely reliable, it happens I'd guess about once a day, always when I am scanning either On Tonight or Upcoming Movies, while I have a PiP quarter window playing some Channels DVR recorded content.
These are all on a 1TB iPad Pro with M2 and latest iOS. They are not the result of resource constraints or anything like that...
Please fix ASAP
