Sometimes you may observe sync issues with Canary. These could include Archive / Delete / Move failure, or slow fetching of new email, etc.
This is most commonly caused by the email provider refusing client requests due to ‘Too Many Simultaneous Connections’, a situation that arises when you are logged in to the same email account on several different apps and devices at the same time.
- To resolve the situation, quit Canary
- Sign out of other apps
- Wait for 15 minutes, and then restart Canary
