Hi @Anonymous,
I can help you out here! Just to check, if you go to the Help menu and select About, what version are you on? You should be on 1.27.0 if you are on the App Store version. If so, then this is the correct version.
If not, my suggestion would be to uninstall the App Store version (save all your data to the cloud first however!) and then reinstall from our website here. The App Store tends to lag behind in update releases due to the approval process by Apple whereas the updates from our website are instant the second we release them. Before you uninstall however, do you mind collecting your diagnostic log files from the help menu within Fusion and posting them here? I'd love to get a better idea of what might be going on.
Thanks,
