I have made a project in excel add-in. There is one issue regarding logo. When I use office default theme the logo is remaining same. but when I use dark theme, the logo will automatically changed. I have attached the screenshot.
Logo in system theme.
Logo in dark theme
I had read all the manifest element but there is nothing any description about this issue. Can we remain same logo using changes in manifest? or There is any way to remain same logo in any theme?
