I'm very sorry for sharing my problem, but I'm not sure what to do now:
Lightroom Premium (mobile) was on discount for € 29,49 (year). I'm actually pretty sure that I did the purchase, but I am just realizing by using the app today that it is apparently not. So nothing else remained to me than do it again, but the price has risen to € 54.99 ... 😔
I checked your account against our system to look for any errors in recent days, and I could find no errors or previous purchase to restore for your account.
A cheaper plan with less cloud storage is shown to some customers in some regions, but if that is no longer appearing in your purchase options screen, there is no way to force that to show again unfortunately.
