Gmails doubled - on iOs only

I have a few Gmail accounts. On the Mac desktop all the right emails come into eM Client - all is well.

However, when an email to one Gmail account in particular is received, a duplicate also arrives at one of my other Gmail accounts. It’s only these 2 accounts affected.

Any suggestions how to fix?

If everything is fine on the desktop but not on the mobile app and you have configured the mobile as Gmail IMAP accounts, then suggest you go on the mobile app to “Menu / Settings” and open your Gmail accounts and remove them via the 3 dots at the top right.

Then on the Mac desktop, go to “Menu / Tools / QR Export” and select your accounts and anything else you want to export and then click export. Then on the mobile app go to “Menu / Settings / Import / Export” and press “Import via QR Code” and scan the desktop QR Code.

Thank you - yes that seems to have fixed it!

the QR import and export is clever - no more manual entry of account details!
