Messages not arriving after leaving airplane mode

[Hocuri]

A user complaining about missing notifications again:

• iOS version: 16.7.10
• Device:
• Delta Chat version: 1.46.5
• Expected behavior: After removing the device from airplane mode, notifications for messages that were sent in the meantime are received.
• Actual behavior: After removing the device from airplane mode, no notifications arrive.
• Steps to reproduce the problem:
  • Set the device to airplane mode
  • Wait until someone sent you a message
  • Remove the device from airplane mode

Not sure if this is a known problem, but since I couldn't find an existing issue for this, I simply created one

After removing the device from airplane mode, notifications for messages that were sent in the meantime are received

usually this is what happens, i just double checked that this is not a general issue:

however, also some notification issues were fixed from 1.46 to 1.48, so this needs a retry or more detailed information.

other common reasons for missing notifications are multi-device, battery- or data-saving modes. also, note sure for how long apple keeps a notification if devices were offline - and how fast apple tried to redeliver

closing, there is also a new testflight, and a new release probably soon (1.48.4); please reopen, ideally with additional information, if the issue persists
