On a new QBO Accountant profile, must I save USD as Home Currency first BEFORE checking the Multicurrency box to avoid getting locked into PHP?

I am a bookkeeper from the Philippines setting out my QuickBooks Online Accountant profile for training. When I tried to change my Home Currency to USD and toggled Multicurrency 'On' at the exact same time before hitting save, the system glitched out, defaulted back to PHP, and hard-locked the settings. Can anyone confirm if I create a brand new account and do a 2-step sequence—saving USD as Home Currency completely on its own first, verifying it updates, and only then turning on Multicurrency—will it successfully bypass this backend regional server lock?
