When you get the next text message (or go to the last one you received), reply with the word:
STOP
and that will cancel the SMS notifications. Once you enroll, I think you can only unenroll by texting back “stop” so do that.
When you first enrolled in the very first text message it tells us it will be limited to up to 5 per month, sharing news, products, deals, and how you can unenroll (text STOP).
For me the recipient code is showing as 71883 so you should be able to send a text to 71883 with the word STOP and that should resolve this for you.
In Account → Notifications → In app Notifications, try enabling it. Are either of the two categories “New Products and Deals” or “News and Updates” automatically enabled when you enable In App Notifications?
I have found that my app does not disable either of those two bottom toggles when I toggle off In App Notifications. It just hides them so that when I toggle In App Notifications back on they are also still on.
It may be that these are still registering as ON even though you have disabled In App Notifications.
It’s a long shot, but it might help by toggling them off before turning off the In App Notifications toggle.
Also, in Account → Notifications → Push Notifications, all the way at the bottom below all your devices, is News & Updates toggled on?
