After the recent release of ChromeOS 89 an issue was discovered that occurred on a subset of Chromebooks in an inconsistent manner. Upon first launching the iTester app some users saw the OSTP for Chrome app rendered in a partial view of the screen instead of in a full screen. This was being caused by an unknown issue in ChromeOS 89. We identified a workaround and updated the app on April 5, 2021. All schools should be able to update to the latest version of the OSTP for Chrome app automatically or through a manual push. Please contact Cognia support with any questions.
