Hi all!
Received the Ronin SC yesterday, managed to mount my Nikon Z6 with the 24-70mm f4 and balance it, and all seems well with the record button on the gimbal.
Early this morning I took it out to film my next youtube (https://www.youtube.com/channel/UCoH5SLI9UsTIhdzDgS9zAaA) video, and as I started packing up, realised the roll arm lock switch wouldn't move to the lock position. It won't budge.
Obviously it's not a masive issue than if it were stuck in the locked position, but if this is faulty I will be requesting a replacement as I've barely had it for 24 hours.

I have the exact same problem. Received my Ronin SC this week and cannot lock this same switch after first use.
During intial set up and immediately after balancing it worked fine.
If you find a solution please let me know.

I'm returning it to Amazon for a refund. I'm going to save up for a gimbal with a higher load capacity, the 2Kg "capacity" on this gimbal is questionable.
