Please send this to Adam - atanner@bryston.com
I've already raised another issue with him (I've lost access to mybryston.com). Once he deals with that issue, I'll mention the other chronic problems per Norco74's post.
I'm sure he's aware of them and I'm sure he's a fine engineer. It's a great DAC! It just seems like he needs some extra help with the Pi Streamer and MyBryston part - the software.
As Norco74 says, you also need someone to talk to us, the customers, and effectively triage the issues for him.
UPDATE: I deleted all my data from my tablet's Chrome (not just the cache) and that restored my access to mybryston.com
