Slow update of chat messages ( Suspected 163mail provider problem )

[fengguowudi]

• iOS version: 14.4
• Device: iPhone 7 Plus
• Delta Chat version: 1.52.2
• Expected behavior: Receive messages in a timely manner
• Actual behavior: It takes a very long wait to receive the message. Sometimes you can't even get a message. You need to restart the app to receive messages.
• Steps to reproduce the problem:
  1.Use 163 mail as the service provider for the test subject.
  2.Send a message to the collaborator. The collaborator receives the message within 5 seconds and immediately replies. The reply contains the current time.
  3.On the test subject's client, observe the situation: if no reply is received for more than 10 minutes, check 163 mail. The reply is already in the folder there, but the INBOX in the client has not refreshed. Forcefully clear the background processes and restart the Delta Chat application to receive the message sent by the collaborator.

can you post the full log?

there should be sth below the ⏸️ ▶️ program-start-emoji -- at least a hint where to get the full log

but the INBOX in the client has not refreshed. Forcefully clear the background processes and restart the Delta Chat application to receive the message sent by the collaborator.

to exclude it is an ui issue: if it happens again, and you enter flighr mode before reatarting the Delta Chat application - are the messages shown then?

closing as there is no actionable item. it is very likely not an UI issue and a - maybe fitting - core issue references this issue
