On the old app on the search and on the main list, they both scroll a very, very long way (never counted, assume it goes to the end) with a slight delay (to be expected) as it loads. Now it stops at 500 on the search and 50 on the web UI.
Just checked on my Samsung S6 tablet on the old app as I recall having a similar issue in the past with the app (on the phone).
If you can provide access to the old app version before this I will check to see if it is the same on the phone as the tablet.
Cheers
