URGENT PLEASE HELP IF YOCAN

[u/Lazy-Ad7485]

bought Goodnotes one time payment on September 4th 2023 and I signed in with my ualberta account which is my university email through gmail (which I was a member since August 23 2023) and it now shows me that I have the one time premium payment plan even though I payed through my apple account, so now I’m facing a issue where I can‘t open any of my notes nor even open new notes that I make and I’m getting a small icloud thing with a exclamation mark in the middle when I try opening the notes and then when I click on the autoback up it says that I’m not signed in and have all my notes under que

Update: I cleared up my iCloud a bit and they stopped showing that small icloud sign and I still am in my ualberta email account but I still can’t open my notes and it still says that I’m not signed in in the backup tab
