I recently switched to Proton and I tried to change my email address to my Proton Mail address here on my VRChat account, but it doesn't allow me to change it to Proton Mail because VRChat doesn't support Proton domains. I was hoping VRChat could allow Proton domains, the main ones being @proton.me and @protonmail.com, as valid email domains. Proton uses multiple domains users can choose from, but the ones I listed are the domains that can be used for free.
