Well the first problem was I couldn’t receive emails consistently to my phone, some would go through and others you’d have to open the app and refresh. ( It never did this on 4G or at my families house ) So that points to it being a problem with my WiFi.
Spoke to someone on chat who accessed my router and changed the channels as it was apparently congested. ( When i first installed the router i changed it to some obscure one which was obviously congested ) and since then my emails have been instant with no problem.
Today, WhatsApp at my home has been playing up, after the phone being on standby for a while it wouldn’t give any notifications unless I opened the app and i missed an important message, hence why i got annoyed with it.
So I went onto BT forum and searched whatsapp. Lots of people recently have had problems with it ( I can post a link if you like )
The solution apparently is to enable parental controls and whitelist whatsapp.com
The problem that was with the phone is " Doze " mode, which i’ve disabled a couple of days back with a script and now i get email notifications 100% of the time even in standby. But what im saying is, this script only works if the phone actually receives a notification. And with WhatsApp it doesn’t. Odd thing is it only does it sometimes.
