Mails received at night not getting fetched

[TobiKatze]

Since I switsched to a Pixel 8, I get the following bug:
Email I receive during the night do not show up in Aquamail. I do not mean "I get no sync at night" - they are just missing from the folder, even after a sync.
The Mails show up fine on my Mailclient on Desktop, but fail to on Aquamail. Synching does not fix the problem. Restarting does not fix it. Only if I move the mails to a different folder - they show up.
Could this have somethign to to with Aquamail missing the initial "push" during the night due to some weird Pixel 8 restrictions?


Using Android 14 on a Pixel 8. Aquamail is excempt from battery optimization (which is also turned off).
Aquamail "Night Mode" where Mails are not synched etc. is also turned off. The screenshot I attached was taken this morning after registering for the forums.

Hi, please write to us at support@aqua-mail.com.

Could this have something to do with Aquamail missing the initial "push" during the night due to some weird Pixel 8 restrictions? - Highly possible, I suggest going through all the device settings related to notifications, restrictions, battery/power optimizations, etc.

Hey there,

it has nothing to do with battery settings, notifications, etc. I can now clearly observe the following:

If I receive an Email on while in my Home WIFI - nothing shows up in my inbox. Aquamail SAYS it synched. I can manually repeat the sync. Nothing happens. The mail is NOT in my Inbox on my phone. But it IS in the Inbox of my Desktop App. And in the Inbox of my Second Email App I installed on my phone for testing purposes.

AS SOON as I cange WIFI (leave my house to change to 4G or disable WIFI in my Phone) - the Email pops up, I get a notifification, I can see it in my Inbox.

BUT: Same thing the other way around. If I get an Email while outside of my home WIFI - nothing happens. The Mail is NOT in my Inbox on my Phone. But on the Desktop App. And the second mobile App.

AS SOON as I connect to my Home WIFI and sync - the Mail pops up in my Inbox.

So: this is not a battery restriction issue, no notification issue. It is no issue with the Ports on my Router (as it happens regardless of WIFI, the important part ist changing the network).
It seems this behaviour is not new, either, I found this post from 2013 (https://www.aqua-mail.com/forum/index.php?topic=871.0) - which sounds pretty similar. Has this been resolved before?
And how do I fix this?

PS.: tried to Debug by pressing on the account name and choosing the last Option (Something like "Diagnosis: Message Time/Date" (it´s german, but you get the gist) and sent it to the support adress.
