Hi! I understand you're looking for the "motion" setting on your iPhone for the Signal app, but it's not showing up. Let's see if I can help figure this out.

Could you please clarify what you mean by "motion" in Signal? Are you referring to a feature in Signal that requires access to motion and fitness data from your phone, or is it something else? Also, have you checked the iPhone's Settings under Privacy > Motion & Fitness to see if Signal appears there?

This will help me guide you better. Meanwhile, on iPhones, the "Motion & Fitness" setting is found in Settings > Privacy & Security > Motion & Fitness, where apps ask permission to access motion data. If Signal isn't listed there, it might not request that permission explicitly.

Do you see Signal in that list? If not, let's try a few quick steps:
1. Restart your iPhone (since iOS 18.1.1 is pretty recent, a reboot can refresh settings).
2. Make sure your Signal app is fully updated in the App Store.
3. Open Signal and check if there is any in-app setting related to motion or fitness.

If after that Signal still won't work and the motion setting doesn't appear, it might be due to Signal not requiring or supporting motion access on iOS directly.

Could you share what problem you're experiencing with Signal that you believe is related to motion? For example, are notifications not working correctly, or is some functionality missing?

Looking forward to your details so I can assist you further!
