I've noticed that verifyReceipt has been marked as deprecated. Could anyone provide information on the specific date when this function will no longer be available? Additionally, if the exact date is still undecided, will developers be notified in advance, such as 6 months or 3 months prior to its discontinuation?

As we transition from using verifyReceipt to the App Store Server API, I'd like to know how we can determine trial-related information such as is_trial_period and is_in_intro_offer_period. Specifically, can we differentiate these details using the offerType value (https://developer.apple.com/documentation/appstoreserverapi/offertype)? Any guidance or suggestions would be greatly appreciated. Thank you.

I have a question regarding the usage of the DeviceCheck API. We have been using https://api.development.devicecheck.apple.com/v1/validate_device_token for checking device tokens. However, we encountered frequent HTTP response status code 403 between 16:50 and 17:15 Japan time on June 29th. According to the official documentation at https://developer.apple.com/documentation/devicecheck/accessing_and_modifying_per-device_data, I understand that a 403 error indicates "The specified action isn't allowed". Yet, I would like to clarify under what specific circumstances this error would be returned. Please note that we do not encounter a 403 error outside the aforementioned timeframe, which leads us to believe there is no issue with our basic implementation.
