I've been using Claude for a long time, and overall, I think Anthropic has built one of the best AI products available today.
But over the past few months, I encountered three product bugs that surprised me.
None of them are catastrophic, but what stood out is that these issues remained unresolved for a long time.
They are not AI model problems. They are basic product experience issues around state management, account recovery, and UI consistency.
1. The UI asks for a verification code, but the email contains a verification link
When logging into Claude:
- The UI says it sent a verification code.
- It shows a code input field.
But the email actually contains a verification link, not a code.
Interestingly, the UI briefly shows the correct message saying it sent a verification link, then switches to the "enter verification code" screen.
This looks like a frontend state management issue.
Not a critical bug, but login is the first experience users have with a product. Small inconsistencies like this make the product feel less polished.
2. The account appeal link doesn't actually let you appeal
My Anthropic account was suspended once.
The suspension email said I could appeal here:
https://claude.ai/restricted
But clicking it redirected me to:
https://claude.ai/new
No appeal page. No instructions.
I also found other users reporting the same issue:
https://www.reddit.com/r/Anthropic/comments/1udfkjv
I eventually had to contact Anthropic support directly via email to get my account unblocked.
Account recovery flows are important. If users lose access, the recovery path needs to work.
3. Updating my credit card worked, but Claude showed the old card
I updated my credit card under:
claude.ai/new#settings/billing
The update succeeded, but the billing page continued showing my old card.
Only after refreshing the entire page did the new card appear.
This looks like a frontend/backend synchronization issue, possibly stale state or a missed refresh after the billing update.
For anything involving payments, this can make users wonder whether the update actually succeeded.
4. Claude Sometimes Floods the Terminal with Duplicated Output
Sometimes Claude Code floods the VS Code terminal by printing the same output over and over again.
This is extremely annoying. :(
5. The "$100 = 20× More Usage" Claim Is Misleading
One reason I upgraded to Claude Max was Anthropic's claim that it offers 20× more usage than the $20 Pro plan.
However, after upgrading, the actual message limits shown in my account were exactly 5× higher, not 20×.
If the "20×" claim only applies under certain conditions, Anthropic should make that much clearer before users upgrade.
Final thoughts
These aren't difficult engineering problems, and none of them stopped me from using Claude.
But they are exactly the kind of bugs that affect user confidence.
To be fair, I already reported these issues to Anthropic's product team through their support email before writing this article.
Mark my words — I'll come back and update this post when these bugs are fixed.
Anthropic has built one of the strongest AI products available today. I just hope the product experience receives the same level of attention as the model itself.
Great products are not only built with powerful technology. They are built with consistent experiences.

Interesting read! These are the kinds of real-world issues that don't always show up in polished demos but can have a big impact on daily workflows. I appreciate that you included practical examples instead of just listing complaints. It'll be interesting to see how Anthropic addresses these bugs over time as Claude continues to evolve. Thanks for documenting your experience!
Actually it's getting worse!
I upgraded claude from v2.1.220 to v2.1.221 yesterday and now it keeps throwing this error, which is a P0 bug.
API Error: Connection closed mid-response. The response above may be incomplete.Now I see that they released v2.1.222 two hrs ago but that issue still persists!
Downgrading to v2.1.220 solved the issue.
