Messages sent via Beeper or Element disappear from Signal Android upon delivery

[ZaeGitHub]

I am not sure if this is an issue with Beeper or the bridge (I don't see how it would be Beeper, but you never know), but when I send messages using this bridge (self-hosted) through Beeper, they show up on Signal Desktop, Android, etc... until they are delivered. Then they, for some reason, disappear entirely from Signal Android. ONLY Signal Android.

How can I troubleshoot this? Are there debug logs I can turn on in the bridge that may explain this?

Steps to Reproduce

• Self-host this bridge, using Bridge Manager (bbctl) to install it.
• Authenticate yourself by sending a message to the bridge.
• Open Signal Android on your phone
• Send a message to someone else via Beeper mobile or desktop
• Before delivery, if possible, notice the message being sent.
• After delivery, notice the message is missing from Signal Android.

Either way, the other user does actually get your message.

I'm experiencing the same on a self-hosted bridge without Beeper. This happens for example, when I send a message over Element (Web, Android, X), so this has to be a bug in the bridge. @ZaeGitHub, you want to change your bug title maybe?

Thanks for reporting this on a separate platform @brknkfr. Changed the title to reflect this occurring in Element too, which IMO does lend credence to this being a bridge issue.
