There is another issue as well which may or may not be related. The timestamp on the Notecard is currently around 7 minutes behind the actual time. The Notecard reports a timestamp of 1751952148 ( Tuesday, 8 July 2025 15:22:28 [GMT+10:00]) but the actual time is 15:29.
I reported a previous experience of this issue here: Card.time request returns incorrect time
The Notecard has remained powered for the past 5 weeks, only syncing via NTN, and other than the issue of only receiving 2 Notes, it has run without any problems.
The Notecard Time issue was supposed to be addressed in the next Dev release and LTS8. Since LTS8 is out and I am running the latest Dev release (Version: 9.1.1.17181), I assumed it was fixed, but it appears not to be.
