Apple Pay not working on safari

I have integrated apple pay in react js using recurly third party payment gateway. Apple pay working perfect on google chrome and mozilla, But not working on safari. The issue is single payment done on safari works perfect but again we tried to pay it shows error payment not completed, Also when tried after some time like an hour or more it works fine again and same thing happens again. Any one know this issue why its happening. Not working correctly on safari. On other browsers it works 100% fine we can pay 10 payments in a row. Thanks for help in advance
