I have Deko 2 on all my UBPort devices and I get notifications coming through for all the emails. The problem I find is that I cannot open Deko 2 from the notifications or delete unwanted emails from the notifications. I also find that I receive notifications for all my days emails even if they have previously been deleted. If you look on GitLab that is where the Deko 2 issues/new feature requests are being logged. You can look there to see if these have been raised before and if not you can raise them.

Same here for both my M10 and E5. I did however have to go into settings and manually force the download, even though I had download update to do automatically on wi-fi.

Update the phone to OTA2 through automatic update, and the phone's operation has improved a lot.

there is a possibility to use script /usr/share/ofono/scripts/offline-modem with parameter /ril_0 which will stop receiving signals from network, so typing in terminal: /usr/share/ofono/scripts/offline-modem /ril_0 will turn off SIM1 ... and to say B-side as well /usr/share/ofono/scripts/online-modem /ril_0 will trun it back on if you want to manipulate SIM2 just use /ril_1 parameter for those scripts
