The useful signal is a silent interface failure: on ChatGPT app version 1.2026.265 running on iOS 27.0.1, “Explore GPTs” is absent from the iPhone sidebar after sign-in. The menu opens, but the expected entry is not rendered, so prompts and model selection will not diagnose the problem.
Which navigation step actually fails? #
The failure occurs at GPT discovery. A user can sign in and open the main navigation sidebar, but there is no “Explore GPTs” or GPT Store option to select. No error message appears, and the missing entry does not depend on a particular model or prompt.
That makes this different from a GPT that fails to respond. Nothing is being executed because the feature cannot be opened from the interface in the first place.
What should be reproduced and recorded? #
The shortest useful reproduction is:
- Open ChatGPT on an iPhone running iOS 27.0.1.
- Sign into the account.
- Open the main navigation menu or sidebar.
- Look for “Explore GPTs.”
- Confirm that the option is completely absent.
The problem was observed on September 30, 2026, in the UTC-3 Brasília time zone. It was described as consistently reproducible rather than intermittent. The attached screenshot was 828 × 986 pixels and 45.4 KB.
A compact support report could preserve the relevant conditions like this:
surface: iOS
app_version: 1.2026.265
ios_version: 27.0.1
observed: "September 30, 2026"
timezone: "UTC-3 (Brasília Time)"
path: "Sign in > main navigation/sidebar > Explore GPTs"
result: "Option absent"
error_message: "None"
frequency: "Consistent"
model_dependence: "None reported"
How should the report avoid guessing at the cause? #
The evidence establishes a missing interface element, but it does not identify why OpenAI removed or disabled that element for this installation. A useful report should not present an unverified cache reset, reinstall, account change, or model switch as a confirmed fix.
The absence of an error message is also important. A report saying only that GPTs “do not work” could be mistaken for a server failure or a broken custom GPT. Naming the exact discovery path makes the problem narrower: sign-in succeeds, the sidebar opens, and the final step—finding “Explore GPTs”—fails silently.
Does the resolved Windows and Linux report matter? #
A related issue was previously reported on the Windows and Linux versions, and OpenAI’s team responded before that report was resolved. That context supports checking whether the iOS interface is using a different navigation implementation or release state.
It does not prove that all three platforms share the same cause. The safer wording is that the desktop issue was resolved while the same or a similar symptom remains reproducible on iOS.
What should happen next? #
The report should include the app version, iOS version, date, time zone, reproduction frequency, exact navigation path, and screenshot. It should also state clearly that there is no error text and no model dependency.
Until a cause or verified workaround is available, the meaningful status is simple: the iOS sidebar is reachable, but the Explore GPTs discovery step fails silently. That is enough to escalate the issue without blaming a prompt, a model, or a nonexistent error message.

On version 1.2026.265, the missing Explore GPTs feels like a UI hiccup that a quick app reinstall usually clears.
