Merging iCloud+ subscription after upgrade - Help.

Hi,

I'm having problems adding my daughter to my 2TB iCloud subsription. She is in the "Family" settings. The thing is - few years back I upgraded her storage (on her phone) to 200 GB and she recetly ran out. And then all the family members - me, my dad, wife and daughter - started getting messages about low iCloud space. So I purchased the 2TB plan - but on my account. I am the Family "organiser".

Now - I can't get to share my new 2TB iCloud with the kid. I still see her 200GB subscription and I can't find a way to merge her into the new plan... Or will this happen automatically when she goes over the 200GB threshold?

Should I cancel my 2TB plan and uprade her plan from 200GB to 2TB and then we still should benefit from that?

Seems kinda silly workflow since I am the parent / organiser...

Please help.
