What issue do you have?

JOPLIN CLOUD TEAM -
Hello, I am a Joplin Cloud Team customer.
We have 3 members in our plan.
My shared notebooks are appearing for members who should not have access to them (confidential data).
Sync is impossible.
I want my shared notebooks to appear only on the correct member accounts, and I need to get synchronization working again
