Welcome to the forum!
You are welcome to discuss Codex issues on the forum, however the official place to report and track them is the GitHub issue tracker for OpenAI Codex.
I used ChatGPT to search for related issues. It found several possible matches, but none that I would consider an exact match.
I suggest searching the existing GitHub issues to see whether there is a closer match. If you cannot find one, open a new issue with as much detail as possible, including steps to reproduce, screenshots or logs if available, and your environment details.
If you find a GitHub issue that matches what you are seeing, consider adding a 
reaction on the GitHub issue page itself. Reactions on GitHub help signal to OpenAI staff that the issue is affecting more users.
Same problem with multiple users, me included. Reinstalling the iOS app does not help.
Found an open issue #23078 (post does not accept links).
No workarounds available at the moment, it seems, so we just do not use this new feature then 
Welcome to the forum!
Thanks for the “Me Too” reply with added details.
I updated the reference to a clickable link.
