Yep, it's pretty stupid!
I honestly don't remember the last time we received the emailed notifications when our items sold (so it was likely years ago by now), but after the split with PayPal, we also stopped getting the emailed 'payment received' notifications, too. Which makes sense, as it was PayPal's system that technically sent those.
I tried to contact tech support about it a year or two ago, but they never figured out the reason why. Back then, those were still supposed to be options that could be enabled/disabled under user email preferences. But with the piecemeal web-code they run this billion-dollar company with, I always pondered if they maybe forgot to disable a legacy version of the original account contact information fields at some point (which likely contain our old email) and that somehow screws with the notification system. As far fetched as it may seem, I actually saw an example of it shortly after our transition to MP last September.
Before the refresh to the invoice system a few months back, the old version had redundant check boxes for which payments you accepted — cash, VISA, etc. — with PayPal having a separate entry field to input which email is associated with the PP account. Prior to MP, that field always had our correct (and current) default PP email, as reflected in our account settings.
... But after MP, that entry field somehow defaulted to an email we hadn't had access to (or used) in well over a decade. Being a redundant entry field, it didn't technically do anything... but I never found a means to make it go back to the correct email, either. It may border on a tinfoil hat level conspiracy, but the fact that some 2k Era eBay database has the potential to override my current account settings has always bothered me.
