Cart Empty While Proceeding To The Payment

The cart is getting emptied while proceeding to the payment. We are using the cscart multivendor version 4.4.2. This happens only on certain devices like OnePlus 5T, 5, 3 and 3T with the Android 8.0 on chrome browser. We aren't facing issues with the other devices with the same android 8.0. Even on the specified devices, this issue persists on the chrome browser and not the other browser.
So the conditions for the issue is
OnePlus devices with Android 8.0 on chrome browser.
Please let us know what would be the reason for this issue. We are losing a lot of orders.
