I've also been having this issue, for the past 3 days or so. First encountered it on my work PC, then my secondary personal laptop (also a PC), and my primary personal machine, a 13" MacBook Pro with Retina Display. Having encountered this across OSs, I can definitely say it is worse on the two PCs than it is on the Mac (go figure). iTunes on the MBP was struggling last night, but a newly added album had been matched by the time I woke up this morning, so it obviously connected to the service at some point. Comparatively, the PCs have thrown more errors and rarely (if ever) connect to the service since the problem began. In all scenarios, it gets caught on "Sending information to Apple" for longer than I've come to expect.
Specific Errors & Troubleshooting Attempts
- Since the outage, attempts to connect have resulted in the "lost network connection" pop-up as well as errors 4001, 4002 and 4010 (all within a 24 hour period)
- Tried: turning off/turning on iTM; restarting computer and doing this again; signing out/back in and then turning on iTM; uninstalling and repeating these steps; probably some other attempts that I'm forgetting at the moment. Basically, no solution mentioned by anyone in any forum I read was working.
- 10% of the time or less, iTunes EVENTUALLY connects to Match, but only after 15-30 minutes stuck at "Sending information to Apple"...
iTM had been running pretty smoothly for months now. I do remember experiencing a similar issue, back in late 2012, which was incredibly frustrating. It may be that Apple is doing some covert maintenance on the service to gear up for September, but it's nonetheless an unnecessary pain. Bottom line is: we're paying for this service, it should work seamlessly. And if not, we need to be notified or reimbursed (I know, this wouldn't amount to much $$ back, it's more so the principle of the matter).
LOVE this service and am happy it's available, I just wish it would work consistently, and that outages would be addressed more expediently.
