twitheatrophonic Just guessing, but I think I remember another app did something similar and a developer said that the app was looking for Chrome's WebView, but since we have Vanadium WebView the app won't find what it's looking for.
If that's the case, the best way to address this would be by contacting the developer or their support to let them know of this issue. Even if it's not that, the issue is likely caused by something on their end.
