Payment is a precondition
A working payment method is as basic as a charged card. Arriving without it turns a simple session into a stalled one. Register the account, link a valid method, and keep a backup such as a second card. Prepared users rarely meet a dead end at the pile.
Fold into routine
Check payment status during normal device checks, not only when a session fails. A quiet monthly glance prevents a loud failure later. After charging, confirm the amount cleared and the session closed. An uncleared hold can block the next attempt unexpectedly.
