Here in Portugal the only thing you need to get an AMEX platinum is a stable income of about 1000€ month and be willing to pay the 75€ anual fee, so much cheaper than Revolut Metal and certainly more prestigious if that’s what you’re looking for
Doesn’t seem to be much thought put into somewhat harmonizing the requirements across different countries
Edit: as for the Revolut forum, they heavily censor it. Stopped posting there as a lot of posts would never get published without any notice or explanation from them. And when I tried to create a topic simply saying a lot of my posts weren’t showing up and it would be nice to at least get some email or other communication stating what the problem they have with my posts might be, that also never got published
