Encountered on iPhone/safari, so may be just an iPhone thing, but…
When I delete all the content from the composer it freezes up and won’t allow me to discard or dismiss. A refresh is needed to regain functionality (and brings back the previously deleted content).
Basic step-by-step:
- Open the ‘reply’ composer
- Type some stuff
- Select everything and delete or cut
Then the composer becomes unresponsive and needs a refresh to work again.
