I’ve just gone into the Starling app (on Android) several hours since I last used it. Usually I’m asked to reauthenticate if more than a few minutes have passed since I last used it. However, this time, it let me straight in, back to the same screen I had been looking at previously.
I happened to have done a transaction search and was on the search results screen.
I haven’t yet tried to replicate this behaviour but thought I would flag it for @StarlingSupport.
