Can not buy the photography plan due to lr free trial os IOS

I tried the lightroom free trial on my iphone and found out that it was lagging many features of the classic. So i wanted to switch to photography plan only to realize that you can not purchase photography plan with Lr subscription still active(Which is kinda stupid imo). I tried to canceled the subscription on my appstore ,but it seems to stay active for at least 7 days which shoulda have been done yesterday on 21 may. Somehow i still cant buy the photography set today a day after the trial should have expired. Is there anyway to fix this?
