Colab limitations

[xRoyBx]

Hi,

when i access SubMe notebook in Colab, i cannot start other colab notebooks simultaneously.

On the other hand, if i'm already using Colab on a different notebook, when i try to connect to Subme notebook i always receive the message:

"Too many active sessions. Close an existing session to continue". This is unlike other notebooks on the web, with or without the use of online GPU.

Is it intentional or it's a problem linked to my account (i have Colab Pro)?

Thank you
