nvm. Got the repo 0.0.79 also to work… trick was SHIFT-R and/or CTRL-R in the grey box… which kind of forced it to reload? and it started working?? wtf?
edit: exactly same trick in WebCord grey box made it also reload and bring picture to it… …
conclusion: must have been some kind of weird “local” discord server or loadbalancer malfunction or timeout or dns_resolve_failure for an hour or two… which caused caching of blank page? and reload fixed it after a while? And there was nothing wrong with the app at all probably…
