AkhilSKumar I have tried all the channels.. community as well as feedback option to get the proper reply on the App Archive features for Nothing phone 2, unfortunately instead of reply on my Q community mod. Warned me and feedback team also keep asking the same queries which I have submitted during feedback ( including log, screenshot). Atleast nothing team should acknowledge this issue atleast.
After loosing the hope I decided to reset my phone and app archive feature is restored now.
