User Profile

I'm facing a weird issue when I try to verify the user subscription, after a logoff/login for example. First I recovery all user purchases, then I sort by transaction date and, in the end, I get the lastest purchase and send the verify receipt to apple endpoint. The issue happens when I receive as response an object with lastest_receipt_info containing an expire date bugged. In my last example, the original purchase date value is "2020-04-07 09:28:06 Etc/GMT", which is correct, and the expire date is "2020-02-10 15:31:35 Etc/GMT" which did my user subscription fail even though the subscription is OK. Does anyone is facing the same problem? Any solutions for this?Thanks!Rafael
