After I've done as following updating sdk35 by B4A sdk Manager. I've test with the real android Phone 11 (it isn't android15) , I don't know that the android Phone11 is about that case, or not?
Currently, I have an Android 11 version of my mobile phone. And I just updated B4A version13.3 BETA#1 to study. After testing with the app, the manifest file was modified to support Android versions of sdk between 21 and 35. it show the message should be34 which isn't 35.
