Static Photo on Mobile App

I have a static photo on my Overview screen that I have updated. Clearing the cache on my PC allowed the new image to appear correctly. On the iPhone, I am unable to get the old image to be replaced with the new image. I have done all of the following:

Under debugging, selected all options

Deleted the server from my iPhone and reconnected

Deleted the app from my iPhone completely and reinstalled

It still shows the old image on the iPhone. Not sure what I can do at this point to refresh, short of resetting the iPhone, which I am not willing to do for one app.

Any assistance or suggestions would be most appreciated.

On your phone, Settings → Companion App → Debugging → Reset frontend cache.

Then go back to your dashboard and pull down to refresh.
