I received this statement from PayPal today:
Unfortunately, due to a technical issue, we mistakenly held some of the funds for your payments, which showed up as a “Pending” balance in your account. Rest assured, you’re not currently subject to this policy and the issue has been corrected. We know this may have been frustrating and apologise for any inconvenience.
Every payment I have received via PayPal in the last 15 months has been subject to this “technical issue”. I think it is about time PayPal compensated those people affected.
