Hi,
Plan Explorer should support SSMS 20.X. First version of v20 branch was released three months ago (mid of March).
Current version 2023.4.3 is not integrated into SSMS 20. There should be a version 2024.1, but it's neither downloadable on the website nor found via updater. Was it pulled?
Anyway, I am afraid that 2024.1 was not prepared for SSMS 20 yet.
Kind regards,
Klaus
