Remote change to colour scheme on a radio app
I was using my radio, for about an hour, and had my iPad closed. When I reopened it, the colour scheme had been changed, and a dialogue box on top which I have not seen before. The only way to change the colour within the app is to go into settings.
My concern is that my iPad has been remotely changed. To my knowledge, my iPad has NOT been jailbroken, and I am NOT attached to a MDN network. My iPad had previously been attacked with a keylogger, and I had to factory reset my device.
How do I check if I have been compromised?
Does this person have root access, as I understand that that is the only way that changes can be made?
To be clear, I have never passed my login details to anyone, nor has my device left my sight since ownership. I have 2FA. I have checked the analytics, and nothing has appeared since May 2023 for this app.
Can someone advise.
