Any former green card holders have issues entering?

Just out of curiosity, with the current climate, are there any former green card holders in here who cross the border often? I'm just curious if you've had issues or any odd questions when trying to enter the US as a tourist afterwards.

I relinquished it through the proper channels and everything, at most I might have forgotten to file my last tax return for the year in which I relinquished it but as I wasn't a resident at tax time and have never worked in the US that shouldn't matter.

Last time I crossed the border as a tourist was 4+ years ago. At the time I was travelling with my (now) wife who had a French passport at the time, so we did have to go to secondary but they didn't ask me about it. Just curious
