Each time I try to purchase 'Realms Plus' on a mobile device (IOS), it doesn’t seem to go through - But when I try to purchase a 'Realms Core' pack, it goes through on the transaction page. (I didn't buy realms core) How come that happens?

Realms Plus Renewal isn’t working.

(Sends me to the ‘Check Connection’ section when it’s literally strong as ever - This frustrates me..)

I tried every different method, searching it up, taking it serious, but none yet that worked.
