JackFou , via OnePlus 6 , Mar 9, 2020 : Recently I noticed that notifications for new WhatsApp messages keep randomly disappearing. Occasionally I see a notification for a new message pop up on the ambient display just to disappear after a second or so. When I unlock the phone, the notification is then still missing. Sometimes it's only the icon in the status bar that's missing (but the notification still shows when I drag down the notification shade) and sometimes the notification disappears entirely and I only see the unread message(s) when I open the app. I hadn't had this issue prior to upgrading to Android 10. I've tried to reinstall the app and clearing the cache as well. I've also checked the notification settings in the app as well as in the android settings and everything is enabled. Has anyone else been experiencing this and/or found a solution?
