I started to realize that some emails in my inboxes dont show in the unified inbox. I dont see an emerging pattern by which emails dont show up. The appear in the notification area of my lineageOS but when i go to check the inbox, some of them are not showing but others are. What could be the culprit?
Btw, i am still missing the old UI with selective accounts and all 
wouldnt happen there…
If I had the chance to choose between those two, I would instantly switch back, so of this is an option, pls implement and give me the choice of what works best for me.
