Thanks for reaching out and thank you for using Crio Pro WordPress theme!
I want you to know that Crio, BoldGrid Post and Page Builder and all of our other products have been thoroughly tested for functionality with WordPress 5.9. You should feel comfortable updating, however if you do find that anything seems out of place on your site after updating use a plugin like WP Rollback to roll WordPress back to its previous version and contact us immediately so that we can report and resolve your issue.
I hope this helps. Please let us know if you have any other questions for us!
