No, it is because you put it inside of an if statement that looks like it will always be false. Even though your anchors persist, your variables do not unless you make them player prefs.

@dbarrett Thank you for reply,there is a flag buildposition,i set it true for first scene.That mean when i open app,and show the first scene,the deleteAnchor is working.But it don't happen.
Okay so how do you know it isn't working? because you are calling it in the start method the position isn't going to change from where it was previously to a new position. It will still be relatively in the same spot where it was before. You need to create another method to move the object to a "default position" after remove anchor is called.
You are also attaching a new anchor right after you removed all anchors.

Also you should try and limit the number of anchors you have in your scene as it is also very resource heavy. The best practice is to have one object as the anchor and have a bunch of children under it. This remains true of course as long as you are in the same room (i.e. 5 meter radius or so). If your objects are farther apart than that then you would need to create another anchor, etc.

Alright, find your WorldAnchorManager in the hierarchy and make sure you have Persistent Anchors checked and also check the Show Detailed Logs Boolean. Run your program again and check the debug this time and see what it is saying.

@dbarrett I reinstall the app without change code,that is working.
