An issue has been confirmed in our application since around April 2023, in which the application's login session is expired.
Our application uses cookies to manage login sessions.
We haven't changed the implementation of the application itself, and we've seen an increase in reported issues since April 2023, so we suspect that iOS updates may have caused the cookie to be deleted.
Is it case that an iOS update could cause cookies to be deleted?
Although we do not know if this information is related to the issue, we confirmed the following points.
-The iOS version that the affected users have been using since April 2023 is 16.4 or later. -Not all but some of the affected users had enough disk space while updating their iOS versions.
