Subscribe new member to a list

SInce I updated from Joomla3 to 4 I am having some problems with subscribers
I also switched from ACY 5 to ACY8

When I manualy enter a subscriber, i can not assign any lists, because there are no lists mentioned.
However, I do have lists!

Also on the frontend, the module is there, but does not accept new entries.
I presume this connects to same problem.

thanx

It sounds like you didn't switch your subscription module from version 5 to version 8

Also, when you manually add subscribers, how exactly are you doing this? From the frontend or the backend?
