Grandfathered licensing and family sharing

I bought Codebook on iOS early on and so was grandfathered into the new licensing. All the members of my family also adopted it via Family Sharing and use it on their iPhones. My license was automatically grandfathered in, but theirs all timed out and they are stuck in read only mode. Is there any process to also grandfather in my family members who were using legal copies via Family Sharing?

Hello @walter1 - Thank you for using Codebook, though I’m sorry to hear about the trouble. Can you send us an email at support@zetetic.net and we’ll see what we can do to help?
