How to clean up after a long vacation

Hi, I've used ynab every day since last year, but I recently went on vacation for a month and I stopped using it. I've tried to use my card as much as possible, but a lot of places didn't accept card payments, so I had to pay in cash quite a lot as well. I was planning on continuing to stick to my budget, but that plan went out of the window basically on day 2.

At this point, I've got nearly 300 uncategorised transactions and it feels quite overwhelming to clean it all up.

What's the best way to go about this and would it just be easier to do a fresh start, since my savings are mostly gone and I get my salary in a few days?

Thanks in advance!
