Account restrictions via “Screen Time” don’t disappear even after disabled? Anybody has seen a situation where “account restrictions” don’t disappear even when removed in “Screen time”

I’m trying to access the apps purchased by my “parent account” in a Family. 

For a while I had “account changes” restricted for the child’s account in “Screen time” so it’s expected not to be able to change/access account restrictions. 

The problem is, I’ve removed all restrictions to the “child” account but I can’t do any changes to iCloud configuration nor does the “account” icon appear in App Store. That means there’s no way to access the purchased apps history, either for the account or for any of the other Family accounts. See screenshots for clarity
Try completely turning of screen time by pressing turn off screen time st the bottom of the page.

How to access your purchase history:

According to this Apple Support page:


  Go to Settings > [your name] > iTunes &amp; App Store.
  Tap your Apple ID, then tap View Apple ID. You might be asked to sign in with your Apple ID.
  
  If you use Family Sharing, you'll see in your purchase history what you bought using your Apple ID, but you won't see what other family members bought. To see what other family members bought, sign in with their Apple ID.
  
  Swipe up to Purchase History and tap it.
