This error means what it says — that we have run short on capacity for that model.
That we understood, I think.
But I guess the problem here is... we pay a plan and that plan does not say "until capacity reached" :)
Many of us buy the PRO priority exactly to not run into such limits.
While I think we all understand things are busy and the plans are likely undersold to what they hold in value, I feel the problem should be addressed, not talked down :)
