Anthropic website always has been user hostile, for years now. They promised a free trial but never delivered it, putting blocking obstructions in the way. They keep logging users out. They locked you out. No one in their sane mind should be using it for anything that is not via API, certainly never for any vital research. For medical topics, I consult both ChatGPT and Gemini, and both work very well. No one at Anthropic has cared about systematically resolving all user-hostile actions.

What's surprising is that you have spent an unbelievable amount of your precious time fighting crap, and this doesn't make any sense. Deleting your data isn't going to save you, so spend time on what will. Surely you have a copy of your data that you can use elsewhere.
