I've purchased MailDroid Pro to connect to my email account via IMAP. I've also excluded the app from battery optimization and don't have data cap set up on my smartphone (Galaxy S9+ on Android 9.0, no root).
When I have the app set to stay connected in Connection Management, then notifications are working fine. However, I'd rather prefer MailDroid to check mailbox every 10 minutes, so I set up some rules to synchronize periodically (the interval at the bottom defines the frequency of checks I suppose?) - see the picture.
Once I do that, I usually get only the first message in those 10-15 minutes, after more time (e.g. 30 mins) I'm not receiving notifications for further emails. I need to open the app and refresh to download a new email. Do you have an idea what the reason is?
