Using the Roku mobile app on my iPhone 15+, iPhone 8+ and iPhone 8 is perfect every time!
I have requested a replacement with an RCS01r as I have not read any errors with that model. I was promised it would be in the mail last Friday by Arun with a tracking number. On Saturday, I was promised it would be in the mail Monday with a tracking number. On Monday, I was promised by Loki it would go out Monday night, and he would personally take responsibility to send me an email with a tracking number. It is now Wednesday, and the only notice I have received is a note asking “how did we do?” I will reserve judgement until I get a tracking number, from Roku, from Loki, and a product in my hand.
