Unity Logo and Splash doesn't change

Hello team,
I’m developing an APP to Rokid AR Glasses, but even though I have Unity Plus License, when I build the app it remains with Unity Splash Screen and the default Unity icon (I changed in the Player Settings). After talking to one developer from Rokid, he said that “This is the rule of Unity, and we guess it may be because the use of Unity Professional edition is required” and would like to know if proceeds.

Unity plus includes splash screen customization.

If you can’t get it working, feel free to contact Unity support.
