I received 3 or 4 emails in the past month saying my paypal is not setup for tips like this: "X would like to show appreciation for your Thingiverse designs by leaving you a tip! Unfortunately, they were not able to since you have not provided your PayPal.me link."
My paypal was provided months ago and i received tips back then just fine. In the settings i cant even unset or set up paypal to fix this.
What is going on and how can i fix this?
