How to fix Netflix not working on my Roku streaming device

Following up on this as well... let's see if I can be relatively organized and systematic in how I describe the issue and steps already taken (although assume anything basic like remove/reload app was tried ages ago).

My Netflix "jams up" for lack of a better term, like others in this thread. Mine manifests as such: starting most any program on Netflix will begin for a short period of time, within 30 seconds, the show will start lagging, the audio will drop out (captions will keep running for a bit), then it'll buffer and eventually overload and the app will reset, or it'll just overload and I'll manually have to press the home button a few times for it to "crash" the Netflix app. Immediately going back into Netflix and trying again, yields the same result. Waiting until later, usually yields the same result.

So... some basic information.  

1) Yes, I have attempted to restart/reboot my TV. Attempted all three of: power button, remote sequence, menu hard reboot. Does not fix.

2) Yes, I have attempted to delete the app and reload the same Netflix app. Does not fix.

3) Yes, I have attempted to reboot my internet, power cycling my device. Does not fix.

4) Yes, I have attempted to connect to an entirely different source of the internet. Does not fix.

5) As far as a speedtest goes, I am on Google Fiber and have speeds of 290down 180up.

6) Netflix is not currently experiencing a service outage (for the past 12 months).

7) My Roku OS is set to autoupdate and updates regularly. It is currently up-to-date however this issue has been recurring for sometime inside of a year, I don't think it's a deprecated OS.

😎I have attempted to go into the Netflix app on my Roku, find the Get Help button, and push reload Netflix. Does not fix.

Answering some basic questions from earlier in the thread. 

1) I noticed the issue starting sometime within the past 12 months. It is a growing frustration.

2) I have four active Roku devices two stream bars, one stick, and this TCL/Roku TV. The only device where this is an issue is the TCL/Roku TV.  I have not contacted Netflix as this issue does not appear to be any other devices. Just one specific piece of hardware, this TCL/Roku TV. 

A simple search of this thread, and then this forum, shows there's no lack of "Netflix and Roku" issues. Is Roku currently acknowledging the volume of recurring/similar issues? Is Roku currently working on fixing this issue?
