Interesting, will have a go at it when I am out for some grocery shopping later on.Since you just got 2.1.6 last week via OTA, it takes time for the OTA system to push the next update. Again, if you aren't having any issues, be patient. The more drive cycles, the more it checks into home base.
One trick is to drive the truck for at least 1 mile/2km, press and hold the service button (to the left of your sunroof controls) until the fast blink turns to a slow blink. That forces the truck to call home and check in. Anyone with remote start/lock issues can do this as well and is the first thing Jaguar technical support does to ensure connectivity is working properly.
Please make sure you're in a good cell service area and don't turn off the engine until the service light turns off.
Thanks a lot.
