Firebase Error on LineageOS

[damnms]

Steps to reproduce

1. Install Element X on a LineageOS mobile phone
2. Start it and login to your homeserver
3. After logging in, an error appears that push notifications might not be available because of "other error"
4. Click on "Settings" and click on "Fix" (i translated them myself from german -> english, so maybe they are not 100% the same wordings)
5. Error will appear

Outcome

No error at all

What happened instead?

An error and probably no push notifications at all

Are you willing to provide a PR?

No

Yes, so what is the exact problem? If you have LineageOS without google apps installed, there will be no Google push available. If you do have the whole Google shebang installed, it should be working.

It says firebase is available and a line below it says firebase not available. My assumption is that the text is misleading, if thats the correct behaviour.
I am not familiar with the push magic behind all those apps, so i assume firebase is the google push server. I installed ntfy as alternative, because thats the non-google push service, right? when firebase is not available, i would expect that to be used. Without an error.
