Mailspring not available as 'default mail client' option on Windows 10

Like the title says. I could have sworn I’d configured it as my default client, but it’s not there. Nor do I have the option to select it from a list of apps (only Windows store apps, because of course :persevere:). How can I fix this?

have you managed to fix it? i have the same issue
thank you

No, still awaiting instructions :frowning: I even tried modifying the registry

possibly no way to make it default which makes it a useless app
