Hey Charlie, I’m sorry this is your upgrade experience. Any chance you could share more details on what goes wrong? we want to make this the best we possibly can.

Hey Andy, mind sharing some of the errors you’re getting? We’re always interested in hearing from our users and see how we can help, fix, etc.

That’s actually pretty good we might use that!

No worries Sam we appreciate the feedback :) thanks for sharing all of that, i`ll pass it along to the team, and we`ll see what we can do. I`ll try to keep you posted and maybe you can give things a try again in the future?

Hey Sam, I’m an EM on the React team at Meta, really curious to get your thoughts on Metro and see where we can improve

I’d like to believe that if you’re building something you have thoughts and opinions on how the thing should look/function. Just prompting “build me a calorie tracker/notes app/music player” etc, without thinking about what makes this different and better makes no sense to me.

Claude did all the boring stuff while I worked on the fun unique features I needed for my player. so awesome. took 4-5 hours in total.

Anyway not sure what I'm trying to say here other than - time flies and life takes you unexpected places maybe?

I always self identified as the "iOS guy" and "startups guy" and then "citymapper guy", and now I'm not only a "Meta person", but a "React person" talk about reinventing yourself 😅 ⚛️

I joined CM as an iOS engineer, ended up doing Android immediately after joining and somehow found myself supporting dozens of reports (during COVID!) It was a pretty wild ride. (Here's me in the launch video for our Apple Pay integration www.instagram.com/p/B5prFHlHuYx/)

Here's a piece of confetti I saved from when we launched Citymapper Pass (www.theguardian.com/uk-news/2019...)
It was the first product at Citymapper I worked on 0 to 1. Took us 3 months I think? People liked it! It worked! It was EXCITING!
