Spell Check App...

I use the Windows 11 Edge Browser and have been using the Outlook Mail App, I understand time is ticking down before Microsoft switches to a New Outlook Mail format.. Under the Old Outlook Mail app I had no problems with the Spell Check Feature, Now that I've switched to the New Outlook Mail format .. Spell Check doesn't work or at least it's not automatically Spell Checking (??) I have 2 Outlook Mail email addresses, 1 Hotmail, 2 Gmail, 1 Yahoo.. Thoughts and Opinions Appreciated, Cheers Thanks
