This problem popped up.a few months ago. Now getting critical. While scrolling thru the program guide on Roku 3 and clicking on selection to get info on program content Tablo/app exits to Roku home screen. My wife has been complaining about this for some time-used to work great. I tried it and it does it for me also. Occurs many times during the day when searching guide.
Occurs on both Tablo Quads we own. Both Tablos are hardwired and the Roku3 is also hardwired to same network.
Older Tablo Quad: Seagate Expansion 5TB.
New Tablo Quad: Seagate Expansion 8TB.
Both Tablos f/w: 2.2.30
Roku 3 4200x s/w version:9.4 build 4200-04
