Alexa+ has been a massive downgrade for me. It's extremely laggy and constantly misunderstands me, whereas the old one never did. "Set a timer for 20 minutes" used to be instant and just work, I did this the other day and it took 10 seconds to respond and set a timer for 10 minutes.

Same here. I can see why LLM-driven voice assistants makes sense to product people in the abstract, but introducing non-deterministic behavior into a device I primarily use to help with timekeeping and control lights is nothing but a regression.
