So this could just be my phone, which is newish, but not sure how?
It's an LG Stylo 5 and it's got all the battery saver things, but I have experience with this from other phones so I made sure AquaMail was excluded from any kind of force closes or stop-running-in-the-background options.
Still I'm getting mails 10 - 20 minutes after they've been sent to me. All my in-app settings seem to be successfully transferred so my important mailbox is still set to instant Push with all the accounts I don't care about set to the usual sync, but maybe the important one is somehow doing a slow sync with the others?
Or it is my phone, something I missed? I don't know, suggestions please. DX
