Currently when viewing an OpenShift screen in F-Droid I see the following notification:
This app was built for an older version of Android and cannot be updated automatically.
I suggest you read the article "Meet Google Play's target API level requirement", which is primarily intended for Google Play users, but F-Droid users will also have difficulty finding, installing, and updating the app in situations where OS security requirements conflict with the user app.
Also, I recommend keeping in mind the changes coming in 2025.
