Hey!
Quick reply about (2). Yeah, it’s a known issue; we reported it to the PsychoPy team. See also this post: Pavlovia experiments used to work, now blank screen - #6 by thomas_pronk
And about the “exports to 2021.1”. I couldn’t reproduce your issue:
- I created a dummy experiment
- Selected “User PsychoPy version: 2021.1.4”
- Synced with Pavlovia
- The version in my JS and on Pavlovia was 2021.1.4
