"Complete your Materials Project registration" pops up every time due to setting error

Today I login in to https://next-gen.materialsproject.org/ with my GitHub account, but “Complete your Materials Project registration” pops up every time I open or reload a page, even if I select
“Would you like to receive emails from the Materials Project?*”
and “Save”.
Subscription seems to have been set up in my /dashboard page, but I cannot Edit Information:

An error occurred while saving your settings. Your settings have not been changed.

@e-kwsm maybe try a different login method in the meantime? Plain email, etc. See Complete your Materials Project Registration pops up when logging in via Google, but not GitHub
