1P8 signs me out of Teams account every couple weeks (Family account stays signed in)

They both use their own unique login password, along with 2FA (YubiKey for primary, authenticator code as a backup option). It's not an issue with unlocking the accounts. The 1P Teams account literally disappears from 1P8 on the desktop. Like I manually chose to "sign out" (except I didn't) and it doesn't even show up in the Menubar > Accounts menu. I have to add the 1P Teams account back into 1P8 like it's the first time I've set it up (even though it's not the first time; been using it for years; only became an issue after moving to 1P8).
