I am not signed up for text alerts and did not follow the pop up. I'm guessing that if you are not already signed up to receive text alerts at your number/account, it may pop up for you, too. It seems to have been triggered when I went to mt account button inside the app.
I don't think Ibotta is using Text Alerts very much. They say we should get up to 7 messages per month. I signed up on October 7, 2020. Since then, I have gotten 4 in October, 5 in November, 2 in December and 3 in January.
Of course, I could be at the end of their list and by the time they get to my name, the information may be old and not worth sending out.
Have others received closer to the 7 messages they say we are suppose to get?
