With the way I link in nearly every post and regularly pay to boost posts and for ads (also with links), it's probably a good thing that Facebook kicked me off. The new 2 link limit would not serve my needs. I need to get people to the book platform. My intent is to grow the audience there so authors gain sales, and it is growing, based on analytics! I couldn't do that if I couldn't direct them off social media.
Keep spreading the word and sharing wherever you can. Even if you can't share a hyperlink, use the images, which include the URL and a QR code. I'm not sure if Meta counts that as a link. (It would be interesting to know if that is a workaround of their new rule.)
