Colab broken?

[demmeler]

Hey together, i just tried to use the Colab notebook with custom images and got the error below, when running the scene cell. Tried it in Chrome on Win and Mac, same error. Should it work atm?

Upload widget is only available when the cell has been executed in the current browser session. Please rerun this cell to enable.

Upload custom images are working fine for me.
Maybe you could try again?

Error seems like it occurs on the COLAB side. The COLAB team might already fix it.

Okay, I tried another browser and get the button. But now the error is:

Same issue

Edit: I fixed it by disabling "block third-party cookies" in Chrome settings
