Sent Emails Still Showing as Sending

Sent Emails Still Showing as Sending

Good Morning All

Hopefuly this will be a quick resolve.

I am using ZOHOMAIL through google chrome, up until a few days ago, all was fine, unfortunately now, when sending emails, the new email just stays there saying it is sending when it has already gone. So in short, the sent emails are not closing down after sending.

I have checked with recipients that they have actually received the email and all is good from that end and they are also apearing in the sent folder checked as being sent but the composed email will sit there for hours and simple won't close itself down.

Thoughts??

Many Thanks in advance for any recommendations or solutions.
