Hey @AndyN both my DB Pro and Wired Stickup cam have been both sitting on this same firmware version as yours ( 2.1.01005 ) since about Dec 10th. I called into support the other day for something unrelated, and she advised that IS the current version even though it doesn’t state “Up to date.” This contradicts every help article on Rings site which states if it shows a version, it’s NOT up to date, so who knows…
In the end, both cameras are working fine so I’m not overly concerned about it.
