I used the free version of Claude for months with very few issues. I got a lot of value from it (non-programming) so I decided to finally pay for an annual plan in the hopes that I'd see better message/attachment size limits, better results, features, etc.The very next day (I paid for the plan late in the evening), I began constantly getting the following message, which I had NEVER seen before as a free user:"Due to unexpected capacity constraints, Claude is unable to respond to your message. Please try again soon."So I tried... and I tried... and I tried. No luck. Claude simply will not respond to my prompt, which is only 3 sentences (and not an overly complex question).I feel like I've been completely bait-and-switched, and there seems to be nothing I can do to get my $200+ back.
