Supported Browsers & Devices
1.Before You Start
Learn with Sumit uses secure video technology to prevent piracy and unauthorized downloads. Because of these security measures, your device and browser must meet certain requirements.
If a course video does not play, follow the steps below.
2.Desktop or Laptop — Windows, macOS, Linux
Use the latest version of Google Chrome or Mozilla Firefox.
Keep your operating system updated.
If the video player asks you to update your browser or operating system, update Chrome or Firefox first.
Windows users can also use the latest version of Microsoft Edge. Edge version 83 or later is required.
3.Android Phone or Tablet
We recommend using the latest version of Google Chrome.
Your device must run Android 5 or later.
If the video does not play in Chrome, try the latest version of Firefox or Microsoft Edge.
You may also use another modern browser that supports Widevine HTML video playback.
4.iPhone or iPad
We strongly recommend using the latest version of Safari.
Chrome may work on some devices, especially those running iOS 14 or later. However, it may not work properly on older iOS devices.
Your device must run iOS 11.2 or later.
5.General Troubleshooting Steps
Close unnecessary browser tabs. Keep no more than three tabs open.
Disable or remove browser extensions related to ad blocking, VPNs, proxies, or video downloading.
Try opening the website in Incognito or Private Browsing mode. If the video works there, one of your browser extensions may be causing the problem.
Close applications such as Google Meet, Zoom, TeamViewer, OBS Studio, or similar software.
Close any software or browser extension that records your screen.
If the video works with a mobile hotspot but not with your broadband connection, check whether your internet provider or network is using a proxy, firewall, or VPN. Disable it if possible.
Disconnect external devices, such as a docking station, and try playing the video again.
We recommend using a desktop or laptop for the best learning experience. If you use a mobile device, follow the Android or iOS instructions above.
6.Still Having Problems?
If the video still does not play, take screenshots of the error message shown in the video player and any error messages shown in your browser console.
Send these screenshots to the Learn with Sumit support channel or contact the support team by email from Help & Support.
