For anyone else in this situation (for nearly 5 months)…
The Shield Experience 7.2 update got pushed today and…it did NOT include a fix for the Link’s IP address bug. I think it’s pretty obvious now why the ST staff has been so quiet on the timeline for the fix. Either NVIDIA has super-long development timelines, or it’s never coming at all.
That said, without this issue I would never have explored and switched over to Hubitat. Been loving it for the past month! Hopefully ST staff start to realize there are consequences to decisions.
