Error: Only one copy of Anki can sync to your account at once

Hi there. I’m trying to sync my Anki on my computer with the Anki on my tablet and I keep getting an error message that reads “Only one copy of Anki can sync to your account at once. Please wait a few minutes, then try again.”

I’m on the same Anki/AnkiHub account on all my devices. Anyone else experience this issue and know how to resolve? Thank you in advance!
