Hey atpdesign, I think you still need to use 2018.2.x with 1.1.1, at least in my experience I’ve only been able to make it work like that. Apparently the app will still work with packs built in 2018.2.x, though they say your mileage may vary. I’m assuming they intend to update videolab from 1.1.1 soon to work with 2018.4.x. Well I hope they do and haven’t just abandoned the videolab aspect of the OP-Z, but thing’s have been a bit worryingly quiet on that front recently.
