It appears that the party has come to an end. If your app encounters a G09 error, don't be surprised, as your account might have been permanently blocked. Unlike before, it seems that 7-Eleven has chosen to prohibit many of its regular patrons.
Contrary to previous practices, the ban doesn't seem to be solely based on your username or account, but rather on your device itself. It's unrelated to your account activities; eg, whether you've travelled between states within a specific timeframe. To me, it's quite evident that they've enforced the app ban based on device-related information.
Perhaps someone could shed light on whether this is the case or offer suggestions on avoiding such bans. It's conceivable that the app might have collected your IMEI or other device identifiers without your knowledge. Some apps might request access to this data for legitimate purposes like analytics or troubleshooting. I'm uncertain if anyone recalls granting such permissions to 7-Eleven or other apps, given that some apps could potentially misuse this data for tracking or other dubious intentions.
I'd appreciate your insights. Where do you plan to purchase fuel from now on? Thank you."
Create buffer by having some fuel cans (if your home can accommodate them).
