The topic doesn’t seem to be closed for me - maybe it was re-opened?
Anyway, I’ve voted for this, as I have a related issue - I simply cannot get my Personal account to appear before my Joint Account. Despite the setting in Labs being on/off. Logout/login, force stop/re-start, uninstall/reset/install, used on different device - nothing allows me to move my Joint account to be after my Personal account in the overview listing.
Must be on my own - it’s a very specific server-side issue for sure - reported here in November last year and in-app last December. No resolution yet.
