I have a Project i created with the shipped firmware and i upgraded to the 2021-02-09 Update.
The Live Loops i recorded into the project seem to load initially, but do not play back and appear to be empty while the A button is lit on each track containing a recorded loop.
I can see and preview the loops on the SD card, and i can get them to load in and play if i change the sync settings around a bit.
I downgraded to 2021-02-08 Update and had the same issue, so now i ended up with 2020-12-16 Update and the problem resolved and everything loads correctly with no hassle.
I also noticed some of my samples had new endpoint clicks in them on the newest updates but are now clean again using the older firmware.
