PWA on iPad doesn’t connect anymore

I’m trying to use Codespaces to develop VS Code extensions, but some issues requires to install Codespaces as a PWA.

Unfortunately, just recently, PWA is not working for me anymore. I open the Codespace I want, install the PWA (Share / Add to Home Screen), the App Icon is added to my Home Screen, but when I open, it keeps saying:

“Preparing your Codespace”

And never connects.

When I entered the Codespaces beta, I was able to use PWA, but just recently, not anymore.

Do you have any tips on how to fix/identify what is going on?

Thank you
