"Plan & billing" or "Profile" → the "Team membership" block → "Leave the team" → "Leave the team". You leave the team you're working in now; with several teams AdFleet opens another one, with none — "No team yet" (/help/no-team).
What happens
- Accounts assigned to you are unassigned; buyers you led are left without a team lead.
- Your Meta auto-rules that could raise spend are switched off.
- Your Facebook profile tokens are revoked, and your Telegram notification channel and goals in this team are deleted — none of it stays with the team.
- The team journal records that you left. Only a new invite brings you back.
The only Owner can't leave — the team would be left without one. It can be deleted under "Data and deletion".
"Check your teams"
If the password was reset through the emailed link while the account's email wasn't confirmed yet, someone else may have joined teams in your name. Then after logging in AdFleet shows "Check your teams": each team shows its Owner and when you joined, with "Stay" or "Leave". If you stay, keep in mind: the Owner sees everything you connect and can "View as" you. Team sections stay closed until you decide.
