The operation couldn't be completed

Hi, I brought a year license on one Mac, and tried to Restore Purchases on another to sync hosts. But got this

It's very likely a problem of the App Store or macOS, please try deleting the app and reinstalling it from the App Store again.

Thanks

I'm on free version and have about 10 SSH profiles. Can I somehow export them and re-import? Because if I remove the app - it's gonna be empty after next install

Your data keeps untouched if you delete the app from Launchpad, all the profiles will be restored after you reinstall Core Shell.

WARN: do not uninstall the app using third-party tools such as "CleanMyMac".

Thanks. Resolved
