New MAX app error: "There's a problem with your device setup"
I haven't been able to find anyone else online with this issue. It seems to be an HDMI issue with the new MAX app.
I finally was able to log in. Now, when attempting to play content, it will play for 1-2 seconds, then picture pauses and "There's a problem with your device setup" and an error code appears onscreen. The MAX web site pretty much blames the HDMI cable, but the one I'm using is HDMI 2.4, and it works fine with the Roku for every other channel up to 4K DoVi (and that includes the previous HBOMax app).
Here's the kicker: I can't play an episode of, say, "Barry", even in 1080p (which is what I'm reduced to with MAX). But... the TRAILER plays fine! In 4K UHD, no less.
My theory is that the MAX app is using a non-standard (or just poorly coded) HDMI check. My signal chain is Roku 4800X > Marantz 7013U receiver > JVC DLA X970R projector, and I'm thinking there's something there it can't handle. The other two Rokus in the bedrooms (hooked up directly to TVs) can play MAX correctly.
Has anyone else encountered a similar problem? Any suggestions to try? So far, I've switched HDMI inputs on the receiver and tried 3 other HDMI 2.4 cables. It's not going through a VPN.
