Usually, this indicates that one or more producers have not linked a PayPal account(s) to their BeatStars account(s). If all producer(s) have linked their PayPal account(s), this may suggest that one or more producer(s) has an issue with their personal PayPal account(s) which they need to resolve on their side. Unfortunately, this is not something BeatStars can resolve as we do not manage the producer(s) personal financial account(s).
If this is the case, please contact the producer(s) directly using the message button or social media options (if any) on their BeatStars profile page(s) and request that they connect their PayPal account(s) where applicable.
