@shredsled, curious to know if you tested at each update interval or only after you got to 2.6?
I'm also interested to know if Innuos support gets back to you over the weekend. They are usually pretty responsive but am not sure if they do weekend coverage. Updates for me have always gone off without a hitch but if they don't get back I will probably refrain from doing updates on Fridays (just in case).
I did the 2.6 update yesterday and it is working fine but I am streaming from Tidal. Just as an FYI, most music streaming services have free trials, you could sign up for one to see if streaming makes a difference? Good luck.
