Since today, when I try to compose an email it will let me type in both the subject and body fields (as normal) but not in the 'To' field to enter the recipient's email address.
I click on the 'To' bit and nothing happens. I hover the cursor over it and try to type - nothing happens. I'm blocked out from entering any email addresses.
It means I cannot send any new emails from my account via my desktop. Seems to be just fine from my phone.
It's bizarre and frustrating and I can't find anything about it online.
Desktop is an older iMac using Safari. Never had a problem before.
