Notifications no longer work (and I've tried the steps on the Troubleshooting page)

Bug description

I don't receive notifications anymore. I've used Signal for years (and love it!) and have never had this problem.

Whether I'm on wifi or cellular, I don't get Signal notifications.

I don't know whether it's relevant, but I think it started happening recently when I traveled to Turkey and inserted a Turkey sim card. I figured maybe that had something to do with it and that the problem wouldn't persist when I returned to USA and swapped back to my original sim card. But the problem persists. The sim card swap could be a red herring, but I figured I'd mention it.

I've already tried the steps at https://support.signal.org/hc/en-us/articles/360007318711-Troubleshooting-Notifications
But I couldn't find this setting on my phone:

Confirm you have enabled WiFi or cellular data while your phone is asleep. Android phone Settings > Wi-Fi > Advanced > Always keep Wi-Fi on during sleep.

And I haven't tried "Reset your Google Account." or completely uninstalling and reinstalling Signal (since I want to maintain my conversation history).

https://github.com/signalapp/Signal-Android/issues/12068 caught my eye, but I don't think it covers what's happening for me.

Steps to reproduce

• Have a friend send a Signal message to me
• Notice that there is no Signal notification, yet there is an unread message in the Signal conversation when I open the Signal app

Actual result: I never see Signal notifications. I need to proactively enter the Signal app to check for messages.
Expected result: Signal should show notifications (assuming I leave the setting enabled), like it used to.

Device info

Device: Google Pixel 3
Android version: 12
Signal version: 5.34.10

Link to debug log

Start by reproducing the missing notifications on the reported Google Pixel 3, Android 12, and Signal 5.34.10 setup, then inspect the supplied debug log and compare the behavior with issue #12068. Done means notifications reliably appear for incoming messages without requiring the user to open Signal.
