Cannot enable MBS 12.2 in FileMaker 20

Is MBS 12.2 supported in FileMaker 20.2+?

I cannot enable it in FileMaker 20.2 (after copying the MBS file into the FileMaker 20 extensions folder) and I hope I don't need to pay $149 to get it working again.

MBS works as expected in FileMaker 19.

Thanks,

Well, please install a version 13.x as they support FileMaker 2023.

And you may email me, so I can find the license and tell you whether we have an update price.

Thank you.
