It might actually just work. The build I’m distributing is a universal build that should work on Intel and Apple Silicon-based Macs. I’m not 100% sure what the minimum macOS version supported currently is.
I would say just try it, but I’m curious what macOS version you are on and if it works. I’ll see what I can do to expand support to older versions if people want that.
Appriciate you taking the time to try it! If you have time time, could you right click and "inspect element”? Then go to “console”. If possible could you paste everything in console in a DM to me? If you dont see “inspect element” as an option, then there is probably something else going on.
This sounds like it might be an issue with the app itself, not BigSur. Might be able to get it fixed easily.
