Can't upload/sync an online experiment

OS (e.g. Win10): Mac Monterey 12.7.5
PsychoPy version (e.g. 2024.2.4 Py 3.8): 2023.2.3
Standard Standalone Installation? (y/n) y

I have synced numerous experiments on Pavlovia without issue. Today I am trying to upload a new experiment. When I click the Run the study online button Psychopy tells me that I am not logged into Pavlovia (I am logged in on a Chrome browser which is how I have always logged on) - Then it gives me the option to signin within Psychopy and when I do with the same credentials that just worked in Chrome I get an error “The authorization server does not support this response type.”

could this be the new we no longer accept gmail addresses thing?

my email is a gmail

then, how do i change my main email with pavlovia/gitlab ?

You need to upgrade psychopy versions.
