Hiya! I haven’t been able to get past https://submit.grantfortheweb.org/submit/164685/call-for-proposals-early-2020. I click the signin button and then attempt an SSO via Google. That works, I’m signed into submittable, but then it redirects me to the GftW page and it’s still asking me to signing. Tested on FF and Chrome.
I resolved it by setting a password and using the non-SSO login.
