Fractal/Matrix MMS workaround

[Kevin Kofler]

Element asked me to download Element apk from fDroid. I think I did that, but I don't see it on my phone.

The PinePhone does not support Android APKs.

I cannot answer the questions because I am not familiar with Fractal, but I doubt Fractal is the answer to your MMS issues.  The instructions in your link set up an MMS to Matrix bridge locally on the phone. That is the pretty much the only way you can receive MMS sent to your phone number in a Matrix client. But it can only work if you can receive MMS on the phone to begin with, in which case they should just work without all that complex set up. (Both Chatty and Spacebar support MMS these days.) If you have issues with, e.g., the APN setup, then the bridge will not help you either.
