Recent performance degradations in mobile Codex/GPT 5.5
OpenAI Developer Community
May 22, 2026
In the past week I’ve noticed a degradation in both performance and app usability with Codex/GPT 5.5.
I’ve been getting the following issues
* Codex mobile app constantly disconnecting with my Macbook
* GPT 5.5 getting stuck in “Thinking” without any progress
* Socket disconnects
Anybody else noticing similar issues?
