GEN 4 Crash When Attempting To View Legacy Units On TV

I have 4 Tablos.

Two networked legacy 4 channel.

One HDMI two channel.

One networked GEN 4.

The problem only concerns the 2 legacy networked Tablos and the 1 GEN Tablo, all used by 3 TVs.

The TVs use the Roku Sticks.

On their own, the legacy and GEN 4 Apps on all TVs operate without a hitch.

Now, the problem I constantly get is with all 3 TVs, while using the GEN 4 App to view the 2 legacy Tablos.

The GEN 4 App has no problem showing both legacy Tablos. But when I attempt to watch anything recorded or live TV on the legacy Tablos, there is a spinning wheel for 30 seconds or so, and I end up going back to the Roku App page. When I attempt to open Tablo TV Gen 4 App, it no longer opens. I have to delete and reinstall the GEN app. All is well until I make another attempt to switch to either one of the legacy units. Then it’s rinse and repeat.

The GEN Tablo has 2.2.58.

Both legacy units have 2.2.60.

The Roku units are:

Application Version 1.3.5 - 734366

Roku Model 3810CA

Roku OS 15.2.4

Application Version 1.3.5 - 734366

Roku Model 3810X

Roku OS 15.2.4

There are no problems when using an iPad.

I have restarted all Tablos, the Roku Sticks, and the router, many times.

Again, the GEN 4 App has no problem finding and connecting to both legacy Tablos, and the crash always takes place whenever I attempt to view something on the legacy units.

Another Roku:

Roku Model 4850CA Ultra

Software version 15.2
