I am facing a very weird Issue in my M2 Store, whenever a user gets back from payment gateway after successful transaction, user automatically logs out from the session and land back on cart page with successful txn message instead of success page.
I do not get this issue at every successful transaction, i have also noticed one more thing that this is happening from Chrome only, when i tried it from firefox i wasn't able to reproduce the issue.
Please guide what could be the possible reason for all this.
Thanks for your help.
