I don’t know anything about it but Berty uses the Wesh protocol. Here’s documentation from their website if you’d like to read into it.

Berty Wesh protocol

I was having trouble earlier but now able to log in just fine on browser. Voting on posts doesn’t seem to be working for me on desktop or apps. In apps I keep seeing error notices about votes not going through and desktop browser (Firefox) doesn’t work but there’s no notification there. Anyone else? Maybe everything needs a little time to sync up.
