Definitely having this issue. I tried to do the raid with some people earlier, and we finished the Spire part with no problems; we get to the Templar area and I start disconnecting every 5-10 minutes with the "monkey" error code. I attempted to keep rejoining, but it kept happening, with seemingly more frequency, so I just bid them adieu. Silly me thought that the Crucible would be any better, so I tried to play a game or two - first game done, disconnect before rewards, go figure. Second game, disconnect halfway through, sit in orbit for a moment, turn off Xbox One, and here I am. After playing WoW for several years I'm not surprised by issues on patch days, but a simple acknowledgement by Bungie about the sudden influx of "monkey" errors (and apparently "pineapple" too, according to a lot of people on these forums as well as Reddit) and a possible ETA on a fix would be really great.
