Custom GPT actions make GPT "not available" on the Android app

I have written some basic Custom GPTs with just instructions and they work fine on the web on my PC and Android phone and on the Android app.

But a Custom GPT that has a custom action, while working on the web on PC and phone, is listed as “not available” on the Android app. I assume this is some permissions thing, since the action is calling an API and Android has strict permissions for this kind of thing.

How do we get Android to give the GPT permission to make and API call or is there some setting on the builder that I am missing?

This has happened to me as well. I don’t know how to solve it but have observed that having actions that require authentication (i.e. to zapier for example) means it is unavailable on android. When I remove the action it becomes available on android so confident this is related.

Had the same problem.
Resolved after solving an error with the action (A problem with the parameter definition).
