Invisible email text in Mac Mail
Hello. I have a late 2014 Mac Mini operating Monterey. For some time with Big Sur some of my Gmail accounts emails weren't showing text - no problem with Apple emails. Affected emails usually have pictures or links because I can see them on other Apple devices. But on Mac Mail these emails show no text or pictures - empty emails. There is something there because a cursor moving over the empty email indicates where there is text and links, and I can activate these links. The Raw Data is also shown to be there. Everything is invisible. Emails that are text-only, even with links, don't seem to be affected. I've tried various solutions suggested in these comments and found online - removing plist, restarting etc but nothing changes. Help!
