Roundcube cant reply to emails but can send individually

Hi,

Been having this problem for a few weeks now, I am unable to click "reply" in emails and have it delivered. In Roundcube, it will get stuck in the spinning sending loop.

However, if i copy the email address and compose a new email and send, it will send just fine.

Any ideas? Thank you

I am now experiencing this same issue. Was there any fix?
