Question Regarding Royalties

Received, signed, and mailed division orders from PRI for three Wahoo State Project horizontal wells in Feb 2021 and received back notice of their receipt. Now, here we are in late October and no royalty payments from PRI. My last contact with PRI representative in early October was they were waiting for their attorney for a release of payment order. Two of the four wells drilled have been in production for over a year. Looks like there are maybe a large number of royalty owners involved. Is it likely that the delay in royalties being paid dur to identifying the large number of potential owners. Eight months seems a long time. Has anyone received royalty payments for production from these wells as of this date? Not sure what next steps should be since I am new to this business. Should I keep contacting PRI each month or have an attorney contact them?
