Hello,

Why would when in M2 composing, Fonts are not in any format ( no format ) during writing.

However, once I click 1 of my account in the " From: ", all fonts in the composing area changed nicely to the correct fonts courier new I set in the preference.

When I click reply all, it was From: my Private account, fonts not the format I choose.

Once I click the From: my other account, fonts is ok.

Why that ?

Thank you very much.
Edmond.
