You hit a plan limit

When you hit a cap, Ples blocks that add and tells you which quota it was. Limits live on the owner’s plan and apply to the whole team.

Which limit you hit

Limit	What it caps
Domains	How many properties you can monitor
Active links	Concurrent monitoring slots. Deleting a link frees a slot
Monthly adds	New links submitted this calendar month (up to 1.1× the link cap). Deleting does not reset this
Users	Team members, including the owner
Pending invitations	Maximum 5 outstanding invites
AI analyses	Analyze Portfolio runs this month

Exact numbers are on Plan limits. Usage bars are on Account.

Free a slot or wait

Remove a domain, link, or teammate you no longer need. For monthly adds and AI, wait until next month or upgrade.
