App does not come up

When I hook my Android phone up to the USB, it does not bring up the App. it only charges the phone. When I go into the app on my own it does not connect.
Been pulling my hair out on this. any help would be apreciated.

what phone are you using

That would be helpful… Android 8.1

The only information you give is you have an Android phone with android v8.1.
We assume you’re talking about the Litchi app?
When I hook up my phone to USB, It does the exact same thing, but I can see it in Windows Explorer.
Think about it and give us something to work with.

It does not automatically bring up the litchi app, when I go into the app itself it states disconnected.

It is not compatible with Autel drones
