I am using Unity 2022.3.15f and Vuforia 10.22.5
I am trying to create image targets by API in runtime and attach quad with video to each image targets

It works well in unity but when i build android version my video player works very bad
where can be misstake? i have simular app in unity 2019.4.0f but there i create targets by database downloaded from target manager in vuforia
