Hulu states minimum Roku software should be at V6.6.3. All my Roku devices are at V6.56 build 3 and current. I'm not experiencing any problems I'm aware of but I just switched to Hulu Live TV and want to insure I don't experience any problems down the road. Are there plans to upgrade to V6.6.3 or higher?
Software numbering systems typically do not zero-pad their numbers.
So version 6.56 is quite a bit higher than 6.6 (think of it as 6.06.)
And by the way, 6.56 build 3 is the exact version I have and it works fine.
What Roku models and model numbers do you have? Settings > System > About will tell you. It will also confirm the Roku software version installed.
Hisense Roku TV C207x model 55R8+ SW V10.5.0 Build 4210-94
Roku Ultra model 4800X SW V10.5.0 Build 4208
Roku Express model 3930RW SW V10.5.0 Build 4208
When I check the software for Hulu, they are all V6.56 Build 3, not V6.6.3 or higher as Hulu recommends.
I hope this helps.
