Forcefully locked out of my documents - Screw you guys

I was avoiding upgrading to Goodnotes 6 because I paid for lifetime access back in 2022 for Goodnotes 5 and I really don’t care for the updates made or a subscription based plan when devs don’t listen to what people want but now you’ve locked me out of all of my documents and say I can’t access them unless I pay???

I tried to use the restore purchases option but despite it showing in my purchase history the stupid app won’t let me. Truly screw you guys and your greed.
