When "Build and run"
MacBook Pro (15-inch, 2017), OS: Big Sur 11.6.1 Safari Version 15.1 (16612., 16612)
Using local server
MacBook Pro with both Safari and Chrome
iPhone and Android on Chrome

Tested and reproduced with Unity: 2021.2.10f1.4301, 2022.1.0b4_0b1e54378c16, 2022.1.0a13.1822, 2022.2.0a4.660

  1. Resolution Note (fix version 2023.2.0a21):

    The internal web server provided with Unit for implementing Build And Run was not supporting HTTP range requests, resulting in all movie seek operations being converted to a seek to start for some browsers (Chrome, Edge). This sever now has minimal support for HTTP range requests that makes it suitable for seeking in the more strict browsers.
