Currently Retail Purchase Categorization uses AI to guess at what category a given purchase item should be. For me it 99.99% wrong.
Either there needs to be a way for it to learn the right categories, or there should be an option to not categorize.
One might question that second part, but what I do find useful even when the category is wrong is the memo. The memo makes it easier for me to pick the right category. So, instead of just turning it completely off not having a category at all would help by the very fact that uncategorized transactions are very easy to find if for some reason I miss one.
