In years of browsing desktop-focused websites on my phone, this is the first website that lags at 2fps while I try to use it. High-end Samsung phone from ~2 years ago (second hand) so cpu power definitely isn't the issue. It also goes back up the page randomly if I scroll a certain way, maybe it tries to lock the view to a certain region rather than in between?
No idea what's going on with that site but I can't check out your project. I'd be interested in a ~two-sentence description of what it's like and how it's different. E.g., is it using the Signal protocol without phone numbers? It so, how's it different from Wire? If not, what does it use, custom protocol? Does it have a description I can look up elsewhere?
