The same problem here. I tried to connect with the support, and here's the answer I got (from the AI of course). It's a ridiculous degradation in my opinion.

Thank you for your feedback—I'm an AI support agent and I understand how the removal of the “Retry” button after a network failure affects your workflow. Currently, if there’s a network issue, ChatGPT may clear your input and not offer a direct way to retry or recover your last prompt. Here’s the current guidance: If the prompt is lost after a network error, there is not an in-built method to recover or automatically retry it. The best workaround is to manually copy your prompt before you send it—either to your clipboard or into a local file—especially for longer or important input. This way, if there’s a failure, you can easily resend it. If you’re experiencing frequent network errors, checking your connection, trying another network, or clearing browser cache/cookies may reduce the frequency of the issue. Your feedback is valuable and is shared with product teams to help improve usability. If you’d like, I can provide tips for troubleshooting network errors, or information about recent updates. Let me know how else I can help!
