Software update - Stuck on last check date

My speculation on the stale "up to date" date is that the date now reflects the last time when Tesla's server made a decision whether you have a new version to install or not. This would allow the server to turn down an update check cheaply and quickly without having to do the (potentially much more heavy) actual update check logic. This can be an effective optimization to reduce their server load.
 
The "cosmetic" date/time checked issue is resolved on both of our M3LR's.

2022.16.1.2 installed June 14th and then we both got 2022.16.2 this morning. Now on both cars, a manual update check shows the date and exact time I do the check. If I sit there and keep checking it every minute the time updates to the next minute. It was not doing this before 2022.16.2.
