Looks like it might be a good reason to hold off on any further purchases until the Matter-verse is a bit more clear, as well as Wyze’s direction with current and future products.
I was all in with the V3 Cams due to RTSP firmware being made available, and that’s been abandoned… I’m not holding my breath for a “Matter” solution in the near future (especially when Camera’s are not a part of Matter v1.0.)
Once Wyze has a new camera on the market that speaks “Matter”… and 3rd party software starts appearing that is “Matter” compliant (aka… ONVIF / RTSP)… then we can all live in harmonious happiness, and I’ll be able to view all of my New V4 or V5 Cams on any Matter compliant device!..
I’ll just need to pay for a Cam Matter Pro Plus Premium subscription to make it all work 
Then again, no further purchases of anything Wyze for me until Landscape View for Tablets is a real thing and not just listed on the Wishful thinking list.
