I have just noticed a change in behaviour when composing a message - I think this has been introduced with version 2018-08-20T08:18:14.777Z.
I noticed it when doing the following:
- Open a message
- Click on ‘Reply-all’
- Cannot delete any of the addresses in the To: field
However, the same behaviour occurs when composing a new message - cannot delete an address once created.
Thanks,
Richard
