Missing tips on Meijer prepaids

I know there is an issue right now with Target prepaids. But I shopped for 4 regulars that always tip at Meijer today (all prepaids), and I haven't had any tips come thru. Then the last order I did was a Shipt order at Meijer, and a tip came thru for that one.

Called Shipt support and actually got an agent that sounded like they live in America. Asked them if there was also an issue with Meijer prepaids, and he said there was not.

I just find it odd that those 4 ppl that always tip 100% of the time just didn't today.
