My vote is to return it.
I have an X mount on my X-T4 and several zooms and primes from Fujifilm, Viltrox, and Tamron.
None of them have any play in the mount after it’s clicked in.
If your other lenses have similar problems, maybe it’s an issue with the body.
Otherwise if this is the only lens with that issue, and others with that lens don’t have similar issues, I would return it.
