Mine sometimes "goes to sleep" for want of a better word. Just doesn't shift when requested. The green light flashes so it's recognising an input from the shifters but it does precisely nowt. Lasts about 30s (might be less but seems like ages at the time), then comes back to life. When it wakes up again it always shifts down a cog, regardless of the click storm I've given it whilst asleep. Then it works fine again. Until the next time.
What was wrong with your RD?

Sound familiar? They've requested it back. Faff!
