eah, ios 15.1, ip11promax, have google-linked to my account, made sure my email is correct, and try to login to all sideloadly apps, but it just keeps asking me to enter login's and never accepts, even if gmail login. Maybe the transition is exp'ing some hiccups.

What version of macOS are you all using? I'm experiencing the same issue, so I'm wondering if it's because I've updated to the latest version?

Im on sequoia 15.7.3 and exact same issue, the sign in screen instantly comes back when you click on it. after 3 or 4 times, it crashes the app, if you don't click anything it seems like the app loads in the background fine but then crashes after a few seconds

Hey this looks like is an issue with the auth cookie from your account, If you're using a google account you'll need to delete your connections in your google settings then re link the account again, Delete cookies and data on your PC.

 

The linking issue is not related to this website but more with your google account and any blockage between the site and your PC, ie any apps you have running, old cookies. Try this:, If you use a browser use another browser like Edge or Firefox and make it default for your PC, then log in. If you log in with the same browser you use for everything is already causing the problem.

Thanks for the earlier tips, which cleared the initial cookie issue. However, I am still stuck. After sideloading the application on my Mac, it fails to trigger the web browser popup required for login.

I’ve already gone to Privacy & Security to click 'Open Anyway' for the app itself. Despite the app running, the 'Login' button does nothing—the browser never launches. 

Since I’ve already cleared my cookies and tried different default browsers as suggested, this seems to be a macOS permission block specifically stopping the app from opening external URLs. Is there a manual login link I can use, or a specific Terminal command to whitelist this app for browser redirects?

Thank you for the report, it bugged out. We will investigate

I have the same issues on my macos. It shows the pop-up requires login, and when I log in on the web browser, it still shows the pop-up. I have tried Safari, Chrome, but it doesn't work

This is a known issue on Mac apps. We still working on resolving the issue

I'm having the same symptoms on macOS,

Problems occur in the "Superstar STARSHIP" and "Superstar SMTOWN" apps,

There is no problem with old-updated apps like "프린세스 커넥트: RE DIVE". (There is no problem even if you erase all the data and reinstall it.)

For reference, the app that has a problem has been occurring since mid-December last month.

Do you need debugging data to solve it? Or is it a problem to pass? @Laxus
