'Start Print' button in popup on CANVAS Hub S did not work

'Start Print' button in popup on CANVAS Hub S did not work.

The Print Jobs just sat there over 10 minutes doing nothing and eventually I have to CANCEL the jobs in order to start again.

It happened every time and I have to use the 'Start Print' button on Palette 2S Pro, then print jobs started straight away.

Please look into this issue and confirm ASAP. Thx:

Hey @tang8555, would you be able to provide an OctoPrint log from a day that this issue occurred (instructions here)? For now, please use the “Start” button on the P2 screen instead of the Hub page. Could you also let us know the exact steps you took before and after pressing the “Start Print” button on the Hub page? This would help us troubleshoot the issue much better. Thank you!

the exact steps I took before and after pressing the “Start Print” button on the Hub page were following all the instructions as shown on the Hub page & P2 and nothing more. Basically SAME as my screenshots. Nothing responded on the Hub page and I have to hit the STOP button on P2 and it went back to START page on P2. I will try and get the OctoPrint log (you may already have them from my other reported problem)

I think it happened a couple of time before but I normally hit the P2 instead since I was next to it. I hit the Hub page these times because I was not next to P2. Thx.
