Deleting emails across all devices
I am having an issue with deleting emails across all of my Apple devices. Both my iPhone and iPad are iOS 14 and MacBook is OS Catalina. If I read or delete emails either on my iPhone or iPad, nothing is indicated as "read" or deleted from the other device, but my MacBook shows the mail as "read" or is deleted. If I read or delete the email from my MacBook, the email stays unread or undeleted from both the iPhone and iPad. This occurrence just happened recently. The email server is through Microsoft Exchange.
I would prefer that from whichever device I delete an an email, it deletes across all devices.
There is nothing on any of my devices which instructs me how to handle deleted emails, change settings, etc. Is this a new bug from iOS 14? Any suggestions are greatly appreciated.
iPhone XS, iOS 14
