Anyone tried 在留カード renewal at Shinagawa office? It was chaos

Renewed my 在留 last week at Shinagawa Immigration. Some real-talk for anyone going: - Got there at 7:30 AM. Already 100+ people in line. - Number system started at 8:30. I was #142. - Total time inside: 4 hours 40 min - They DID accept my online pre-application, but still made me wait - Tip: Bring water + snacks + portable charger. Next time Im doing it through 行政書士 even if it costs 30,000 yen.
