After upgrading server key, the client is unable to receive (silently) and send messages until relogging-in

[xuhdev]

Describe the bug After upgrading server key, the client is unable to receive any message silently, and when sending messages, the messages stay gray and I won't know it can't succeed until I tap the message.

To Reproduce Steps to reproduce the behavior:

1. Log in.
2. Upgrade server (synapse) key (using let's encrypt), and restart synapse.
3. Open the android client.

Expected behavior The client should either work properly, or if the new key has an issue, it should pop up and ask about the new key.

Smartphone (please complete the following information):

• Device: Galaxy Tab S5e
• OS: Android 10

Additional context

• App version and store: 1.0.11 [40100112] (G-b847)
• Homeserver: private

This is a known limitation from 4bb804fbf7664adf593147d2c5ddc34200417ab3 (advertized here: https://github.com/vector-im/element-android/pull/1570), and correspond to that TODO: https://github.com/vector-im/element-android/blob/develop/matrix-sdk-android/src/main/java/org/matrix/android/sdk/internal/network/Request.kt#L58

It was not P1 but I agree it has to be handled properly in a near future.
