I updated the Tapo H100 Hub 12 hours ago to Firmware 1.5.23 Build 241106 Rel.093525.
Since the update, the hub has been losing connection / offline in app (solid orange light on device) approximately every half hour.
I have had to unplug and plug it back in seven times so far but have now given up on it.

The hub was working stable before the update and is essentially useless now.
