If this was only one model of TV i.e. TCL, that had the issue i would be pointing fingers to TCL, but when you have several different Brands having the issue then it is software.
Speaking as an IT Engineer with almost 20 years experience i can safely tell you that when different hardware has same issue then it boils down to Software.
Reasons for older Roku's still working is they use to work and were patched to current level.
Reasons the newer ones do not is the needed file(s) are either not there because they were deemed not needed but patch if found or the newer version with out the older runtimes fail to load the connection.
Like it has been said this issue is limited to Google Home and Alexa connections to TV.
Roku Remote app and Apple Homekit works.
and here is a kicker, Home Assistant works as well.
2 of these are true
Only 2 of these are true right now. so Roku is 50% correct.

Yes, this is a very interesting issue. I have 2 new Roku TVs purchased in the last 2 month (an Onn 32 inch and a Hisense 58) and both have this issue. Still have 2 older functioning Roku TVs in the house (TCL and a Hisense) purchased about 2 years ago that are still working fine, but these new ones just will not work with Google Home (Roku app is fine). The whole point to getting one of the TVs was to display a family calendar (through PC input) most of the time with the intent of having a Google Home routine to turn the TV on at a time in the morning and off later in the day, but obviously with these issues, that routine always fails since they will not do anything through the Google Home app ("something went wrong" error every time).
FYI, Good News
My new TV is now working with Google.
I did not change anything other than have a ticket open with Roku.
I told Google to Turn Off the TV's thinking my other 2 Roku's would turn off as normal and the Living Room TV turned off as well.
I then started using commands specifying my Living Room TV and I can verify all is now working with Google.
I am seeing the same thing myself for both Alexa and Google Home integration.
Thanks to whoever dealt with the challenge.
We are now able to control our TCL TV with Google Home!
Most impressed.
Well pleased!
Dang it! I am the one who started this thing and I still cannot access my TV...Not fair!😞
I just confirmed that my two newer TCL TVs are finally responding to Google Home as well.
What I had to do initially was turn both on manually (as one showed offline in GH and one was still 'Something Went Wrong'ing), then their status showed as 'On' in GH. Turned them off in GH, no errors. Tested voice commands with my Google Minis and those are working too.
So it seems that some new firmware is being pushed to at least the TCL Roku TVs at this point. For anyone that doesn't have it working yet, go into your TV and check for updates, there may be one waiting for you.
Can confirm it is working here too. Thank you for making this right.
