Unity Icon appears on App Icon after updating Unity Version from 2020 to 2021

Have a nice day folk,

We have been facing an Icon problem after upgrading to version 2021. As you can see a Unity Logo appears above our app Icon. What is the ideal way to fix it? Has anyone of us faced before with this issue before? Cheers,

Footage of issue:


Tried removing and adding back the icon?
And what unity version? Latest lts?

is this a bug? or setup issue?

Same issue, is this an engine error, a configuration issue due to not having a paid Unity account, or an error on our end that we can resolve in the project settings?
