Starting this morning, whenever I try to reply to emails on Windows 10 Mobile from my Gmail account, the send email button is greyed out:
The funny thing is that if I create a new email, then the send button is not greyed out. Also, I keep receiving emails without issues as usual, calendars and contacts are working fine etc, so the only issue is I cannot reply to emails.
I haven't found anything online so far (nothing recent at least), does anybody have any idea how to solve this (ideally, without deleting and readding the account).
If it helps, this is a Lumia 640 XL.
