I built a bot now on my phone, and I have been trying to publish it for more than an hour. But the loading spinner keeps rolling till eternity and not publishing. Please help.

are you using Safari on your phone? I'm not sure about publishing on mobile but it's a known issue that the button hangs on Safari

If you're on iOS though then Chrome is still using the Safari engine so you might face the same problem

I’m having the same problem trying to publish from either my iPad or MacBook Pro, using either Chrome or Safari: Publish never finishes.
