Hi all 👋. Thank you for your patience whilst we tested and debugged the issue.
We have successfully identified this issue as a regression in ACF PRO 5.9.4 which caused ACF Blocks to be registered *after* the WP editor instance was initialized. This explains why new blocks could be added whilst existing blocks did not appear on page load.
Whilst we continue testing of the fix, please find an updated JS file to copy and paste into the pro/assets/js/ folder within ACF PRO. This file contains the related patch and should solve the problem 100% – please comment bellow with your results. The quicker we can get positive feedback from you, the quicker we can release an update 🙌.
