Does Teslafi interfere with "stop charging"?

I noticed yesterday when charging my model Y, that when I clicked on "stop charging" in the Tesla app (Android), that it stops charging, but a few seconds later, charging starts again. The only way to get it to stop charging was to pull the max charging percentage into the green area to force a "charging complete". Since after stopping the starting to charge is not immediate, I am thinking that it might be a Teslafi issue rather than a Tesla issue, though of course it could be a Tesla issue also.

Is anyone else seeing this?

Thanks
