The business authentication of the business portfolio (BP) associated with the original app (A) has been suspended, and the BP has been reassociated with a new app (B).

A: Necessary BP x 3, BP x 1 suspended, API suspended B: Necessary BP x 3 (same BP as A) are connected, API normal

I would like to use B in the future.

In light of this, I have the following questions.

1. Is it necessary to detach the necessary BP x 3 from A? 　If so, do you know how?
2. Do you know if there is any other work that needs to be done in order to use B in the future?

Thank you in advance.
