Ouch! So sorry for that, you used the native app? Or you used your browser? If you used the browser I would say it's more your computer that has an issue :(
I totally agree. The technical reason is I enabled WebGPU which resolved most of the performance issues I had. When loading sometimes it's my entire chrome that is stuck and that's a shame. I'm thinking on enabling WebGPU only on macOS and Linux computers and keep Windows running WebGL to solve those kind of issues you have. I'll let you know via the devlog :)
And sorry again for that, I'm really concerned about it and I'll come back with a solution
