How do I set the zwift screen resolution on a S8

I am using a Samsung S8 to run the application and then mirroring it to my fire stick TV. how do I set the screen resolution so that I can read the controls currently they are so small I can’t see them let alone control them

There are no resolution options when using andriod. Try change the settings on your TV?

so I bought an iPad, but now it won’t log in. Tried resetting the password (from my PC), but it still doesn’t work.

The first step in the process is to activate mirroring on your Fire TV Stick. Go to your Fire TV menu, hit the Home button, and move right until you reach Settings. Navigate to Display & Sounds, then choose Enable Display Mirroring.
