Tripod collar ring wont tight/lock... Nikon Z400 2.8

[marc]

The tripod collar ring attachment screw can get "stuck" at the ends of its rotation - I "VERY GENTLY" used a mole rip to "loosen" mine when it got stuck and then it worked fine. Just try not to "over-tighten" this screw at either end (loose or tight) -- all it is doing is applying friction to stop the lens camera rotating - it is not supporting anything so can be fairly loose.

I wish it was that simple Andrew, but that is clearly not the case for our issues.
Will be sending mine back to Nikon once my 2 trips are in the bag at the end of FEB, fortunately I won't be using mine on a tripod so it can wait until then.

Same thing with me, just received my Z400 2.8 and can't tighten locking nut sufficiently to lock down collar. Hopefullly as mentioned above will be a quick fix.
