Private Direct Messages DMs seem to be the way... But there is 2 ways to send one I believe. 1. Once logged into this Forum, look in Upper Right corner at top of page to see some icons... Between the Bell for Notifications, and your Avatar pic fie your Settings, should be an Envelope Icon (if youve visited and read enough to be at least Level 1)... Click this to view your Msgs, then click the New Message btn to send a new DM.
2. In a msg thread, click the name or avatar view their user profile, then click a btn on that page to send a DM to them.
I have a standalone 4660X and just ran an update, and it downgraded the system from 10.5 to 10.0.0 4209-46. After that, I ran another system update and it had 54 updates, which I guess is downgrading all of the channels that got updated after 10.5 was released.
For the record, I didn't experience any issues with 10.5. In fact, I think my device ran better. Again, I have the 4660X standalone (Roku Ultra 2017).
I run manual updates all the time, I ran one earlier today and there were no updates... so for me, the rollback happened just today, in the late afternoon.
After getting in touch with CS I asked them to roll back my update to the previous software version, it took a couple hours but I just check my update section on the Roku TCL tv and there was an update waiting to be installed Version 10.0.0 build 4209 - 30 It now works perfect again on all apps is lightning fast once again!!
Well Roku IS offering to help folks get back to OS 10.0 build 4209... Read my Solution Steps in previous responses just below /earlier, or those steps detailed by Roku Employee RokuDanny-R. Basically send him a Private Msg thru this Forum with your devices specs and IDs, he will reply with steps to recheck and get a manual Rollback update to reinstall and reboot. So far those like me that have got it have seen their devices restored to previous good speed and response times.
