Why does my private collection revert back to a no-access page?

Hi I just set up private collections so i can select the access rights for our different customers.

I followed the steps from Sunbowl Systems and everything worked - https://www.sunbowlsystems.com/blogs/how-to/how-to-create-a-private-collection-for-tagged-customers.

I tried to test it and even though I tagged myself and the products to access the collection, it still revert back to the no-access page.

Why is this the case?

Hi. Did you ever work this out?
