As a workaround, you may try to set the spellcheck to a different flavour than your system language. E.g. when your system is configured to use “en-US” as a language and provides its dictionary, then “en-GB” might work.
I will monitor the issue and hope that a solution is possible in the future. For now, there is not much that we can do on the side of Mailspring.
Thanks for this reply. It doesn’t solve the problem, but it gives hope that you will eventually fix it. This is the main blocker against the decision to go for the paid version (although the price is also a bit too high, $5 would be a reasonable barrier - for example, the whole Google Workspace costs $6/month) . Maybe some kind of -50% promo on BFCM? I would jump into the annual package hoping that you will soon fix the bug with the lack of language correction.
