Instagram app has been crashing for some Android users this week, and it isn’t clear why. Issue started happening around April 13th, 2021, when the Instagram app on Android devices received its latest update. Users took to Google Play store to report their recent experience with the app. In tests by BleepingComputer, clearing the app cache and storage, or even reinstalling it did not seem to resolve the issue as of a few hours ago. This issue comes after Instagram was down in an outage just a week ago.
