I finally found what was causing my problem I think. I recently obtained an iPhone 6 hand-me-down and in setting it up I neglected to turn on WIFI usage in addition to just the ATT phone connection. You must have all devices on the same WIFI network, install the applicable app on your Apple device (HBO Max in my case), set Airplay to on and whatever setting you want for access (ie code once only, always, or password), open the app, find the tv show you want to stream, click on the Airplay icon, select the Roku device you want from the list (I have 3 in my home), enter the code for the specific Roku device that appears as requested or password if that was your choice, then click on the Play arrow in the HBO Max app. Is it simple or user friendly? You decide. If you have Airplay as a choice on Roku Setup and an Apple device (phone, tablet, laptop, etc.) you should be able to get it to work. I got HBO Max for a year for free with my ATT high speed internet connection and I wanted to binge Sopranos.
