The new online system in 2021 worked great for me. Many of the people having issues didn’t read the instructions carefully. You had to have the My Wimbledon app and your ticketmaster account. Yes the online ticket queue was long but I got a ticket for manic Monday. The ticket showed up in my app. The only thing I didn’t like was that the QR code on the app does not appear until the morning of your visit which caused me quite a lot of panic! The actual venue was really well organised with lots of staff to help.I literally walked straight in - COVID status proof on the NHS app. Wimbledon has a magical atmosphere. Due to COVID (I think) 5 courts were ticket only so spent a bit of time on The Hill watching centre court matches on the big screen. Even the parking was well organised. Apart from my favourite player losing, I had a brilliant day!
