Installing Seller caused my Messenger push notifications to stop working I have encountered a serious notification issue after installing and signing in to Seller. Before installing Seller, my Messenger notifications worked normally. After installing Seller, Facebook Marketplace messages started being delivered to Seller with notifications, but Messenger push notifications completely stopped working. Even after I deleted Seller, the problem with Messenger did not go away: Messenger still receives messages normally; However, there are no lock-screen notifications, banners, sounds, or notification badges; The messages only appear after I manually open Messenger, at which point all previously received messages suddenly load. I have already checked and confirmed that my iPhone notification permissions, cellular data access, Background App Refresh, and other relevant settings are all enabled and working correctly. I also deleted Messenger, restarted my iPhone, and reinstalled Messenger, but the problem remains. Notifications from other apps work normally. This strongly suggests that there may be a notification conflict between Seller and Messenger, or that Seller changes the push notification routing associated with the Meta/Facebook account and does not properly restore Messenger notifications after Seller is removed. Please investigate this issue as soon as possible. Seller should not interfere with normal Messenger notifications, and deleting Seller should not leave Messenger unable to receive push notifications.
