I just acquired a TiVo Stream device to go with my Roamio OTA 1TB (with cable card) to get the one thing I'd been missing. I got one on ebay and have it plugged into my network. The first challenge was that networking devices was disabled on my TiVo (according to tech support) so we turned that option on. However, all attempts to set up the TiVo app and have it connect to the device fails on Step 2 (validation) on my Chromebook and my Galaxy phone. The device was previously assigned to the ebay owner and they changed that over this morning. Perhaps it takes more time to get it onto my account? I don't see why... The one thing I've learned from all of this is that support is not much help.
