So, Recently, we got the android Pie update to our mate 10 pro. Unfortunately, Ever since the pie update, I no longer get messages pushed through unless i'm actively in the app. It's caused me to miss a lot of messages. Before i hit the nuclear switch and hard reset the phone, i'm trying to find whatever hidden setting is there. Yes it's whitelisted from any and all battery optimization apps. Yes, I have unlimited data. Yes, I've cleared cached, uninstalled, and reinstalled Messenger. Literally every single whitelist setting I could find, I've checked it off. It's similar for Kakao talk, but I do get all my Slack notifications pushed through (Ironic, since I was running into problems with slack on Oreo) does anyone have similar problems after upgrading to Pie, and if so, how did you solve it?
