This one took a bit, it requires bumping lib XMTP, also included in the push notifications PR

What this means is old addresses made with the current TestFlight will not work, which is a pain, but should be a one time/alpha pain

[alexrisch]

This is fixed in the latest TF However to reiterate, only accounts made on this testflight and future ones will work
