For example, I had to recently change an env var we had on a handful of apps and opened them all into new tabs and made the changes and about half way through I started getting rate limited. This has happened to me many times and I've reported it to support and in Discord but it still happens.
One other big complaint is support is non-existent. We sent many support emails (on business plans) and I'm pretty sure we've never gotten a reply. Same for posting in Discord. It's pretty disheartening to build your business on Cloudflare and have no confidence support will help you when you need it.
as far as support, i know there is a huge effort going on right now to improve response time and support in general, also I'm not as active in discord as I ought to be there's just so much noise, feel free to ping me on there directly if I can help brandon/@ygwyg. can't promise it'll be an instant response but I will respond
