Before I reset and re associate, I was wondering if support can comment please? The tag is not reliable because of this inconsistency.
Thanks
This is the first time we heard low power mode makes tag unresponsive. I looked at your account, I think it is because you have chosen "Disable auto-update". Tags use auto-update to periodically communicates with the tag manager to internally compensate for frequency drift of crystal that may be caused by temperature change and aging. I have changed the code so that if auto-update is disabled the server will not attempt to automatically set low power mode (which we do after 1 week of non-user interaction).
Please apply a flash reset again and set an auto-update period 1 hour. At this interval the battery drain is really negligible.
