Yesware 'Processing Message' Pop-up & Potential Email Duplication

We are currently experiencing an issue where some Outlook users are reporting a pop-up when sending emails using Yesware. Affected users are seeing the message 'Yesware is taking longer than expected', and are prompted to either 'Send Anyway' or 'Don't Send'. Upon selecting 'Send anyway', these users' emails are being sent an additional time, while selecting 'Don't send' moves emails into the users' Drafts folders. At this time, for those affected, we recommend selecting 'Don't send' when prompted by this pop-up and deleting the subsequently created draft copy. This will ensure emails are only sent once. Please note, email tracking is not impacted by this behavior and emails sent will collect engagement data as expected. Our development team is actively looking into this and we will provide an update once we have more information.
