How can I change the PsychoJS version from 2020.2 to 2020.1?

Description of the problem:
I have chosen the version 2020.1 on Psychopy Builder and synchronized it with Pavalovia, and it showed the synchronization was successful. However, the PsychoJS version in Pavalovia did not change.

Thanks.

I am not sure about what I say but I think that the online version is not changeable unlike the offline python version.

Try setting the experiment to inactive and then active again

Hello,
Thanks for your suggestion. I have tried your way, but it is not working. It is OK. The purpose of changing the version is because I want to use a screenscale template created in version 2020.1. I have deleted a statement, which causes the screenscale template to not work in 2020.2.
Regards,
Chen

I’ve also updated my screenscale experiment to 2020.2 (by deleting the same line)
