"Unable to Complete Request" error

Hi everyone, I’m facing an issue with my app version (changed Subscription from weekly to monthly) being rejected due to a "Loading Subscription" first time, then "Unable to Complete Request" error in the SubscriptionStoreView. I noticed on the screenshot that the review team was using a VPN, and since my app isn’t available in the EU, I believe this may be related to the problem. I cannot replicate the issue on my end in UK. Does anyone have advice on how to address this? Thanks in advance!
