We need to distinguish between the two attempts, I also think there are several issues. First attempt I picked “general item”.  I asked for a listing title and a category. When selecting the category, I ended up in a pop-up like your #2. I drilled to Safety. Selected it then got sent back to the start, with the listing title as I had input but without a category. It was a loop I could not get out of.  Bug 1: The “what are you selling” list should not include categories not available if you have picked “general listing” at the first step i.e. all the car stuff.    Bug 2: The category select...

It worked in a different category. Seems you can sell snow chains as a sporting accessory but not as a car safety feature. The "select a category" list seems to include categories where listings are not allowed.

Trying to start a new listing and TM won't let me add a category, so I can't start the listing.  This bug is still there. Can start listing, specify title, get sent into a series of pop-ups to drill down to the category, select a category, back to where I was with no category selected. Website, laptop, same issue under safari and firefox. Desired category was TM Motors > Car parts and accessories > safety.  The "search all categories" for safety also failed to find it.  Something wrong with your indexing.
