I had the same issues with the first Marantz streamer, the NA 7004.
oh, and the controlling app was terrible. I know just use it as a DAC in my 3rd system for Apple TV. I had the same experience with their product support, as the various fixes were useless. There were firmware upgrades, and invariably they would cause 3 new problems for every one it fixed.
Marantz just can't do streamers. They should drop out of that niche. I understand why they want to stay in that category, but after learning that my issues were common amongst users, I swore off all Marantz products, even though I do like their house sound.
I use Bluesound now. Not perfect, but a lot less buggy than Marantz
