One of my favorites amongst this stupid platforms is PayPal. I have moved countries/continents. Once I forgot to close my account before moving (still had some $100 on it), after I could never access it as it wanted a phone call to my non existent former phone number to confirm this is really me, ok my fault. Now I have moved again when I want to pay with PayPal I can't because my account is associated to a different country. It is impossible to change the country. The FAQ say you have to close and reopen a new account), but if I try to close the account I get to an error page. This would all be not so bad if it wasn't for the merchants who use PayPal and disallow payment without an account. In the end the easiest was to just open a new account with a different email.

Somebody mentioned Google services, and that was a big issue as well. I still have bank accounts in my former country of residence, so I need access to apps from that country (the 2fa App that is used there). On the other hand I need to access some apps here (school notifications, banks...) Google obviously knows better than to allow me to get apps from different regions. The solution was again to just create another account. The whole system is really screwed up. I'm not sure what they are actually trying to prevent, considering that in the end one can work around the restrictions quite easily with multiple accounts, but one would think with the world moving closer together these things would actually get easier.
