i'm sure title read weird but that is what i have witnessed few times on my p8, and just now actually tool actions in each of the opened apps, but it didn't last long, in few moments one of them collapsed and disappeared. obviously i was not expecting it to continue running twice at same time further. but i would like to know what might be causing this behavior. apps in question are Appmanager (couple times i saw it running itself in parallel with the one that i was at that moment using, i noticed the second one in recent when was switching to another app. then i did not try to actually manipulate them both and just shut one down) ., and Vanadium just now, i opened from the home screen and instantly noticed that the tabs opened are different from what i left there just few minutes ago for a moment one tab from precious session appeared open i managed to quickly prompt the auto fill credentials and it closed and i was not seeing it among the tabs ,and the tabs i was seeing were from earlier session maybe a few hours old like from morning, on recent a momentarily noticed an open Vanadium's crash report that took place early morning. i close Vanadium, reopened and was surprised to to now see the correct session only , i then went to recent cleared and reopened Vanadium again, now all as expected.
in simple it looked like Vanadium had a flashback for a moment and shortly got back to normal.
i know it is a very vague description at least i would think so if i came across such post. but I tried to be share all i saw it on the screen. i am sure that somebody who experienced same will understand.
