Samsung S6, all current updates done.
Recently started having issues not getting Facebook Messenger notifications at all until I open the app. When I open the app, it quickly says "Waiting to connect" for a few seconds, then says "Connected" and then any notifications pop up, in some cases from hours before. Have deleted both the Messenger app, and facebook, re downloaded them to the phone, restarted the phone, SIM pull, etc all the basic stuff with nothing making a change at this point.
I have also had Gmail issues for about the past 2 months. I dont seem to get a notification until I have a second email (at which point the first may be an hour or more old)or it seems if I get an email while on Wi-Fi I NORMALLY get the notification right away. I also get a notification on my phone the second I open Gmail on my desktop.
Looking for any possible solutions. Have looked through my settings, nothing glaring to me that seems off. I am in SW Ontario with no connectivity issues to speak of.
