Videos, browsers, phones, emails
- A video will not playIf the player keeps loading, your network is probably blocking YouTube: try another network or your phone's data. If the player shows an error, use Open it on YouTube.
- Which browsers and devices work?An up-to-date Chrome, Edge, Firefox or Safari, on a computer, tablet or phone. Keep cookies switched on so you stay signed in.
- Can I learn on my phone?Yes. Lessons, notes, quizzes, your portal and the checkout all work on a phone. Course software such as TIA Portal installs on a Windows computer, so do those practical steps there.
- Our emails are going to spamSearch your spam, junk and promotions folders for EDWartens and mark our email as Not spam. Adding the sender to your contacts helps.
- A page will not load, or the site is slowReload, try another network or browser, and switch off extensions. If it still fails, send us the page address, what you saw, your device and browser, and a screenshot.
- How big can an uploaded file be?It depends on where you upload: a CV or resume up to 10 MB, a profile photo up to 5 MB, a portfolio picture up to 8 MB, and internship or job simulation hand-ins up to 25 MB per file.
- The 3D Lab says it needs WebGLThe 3D view needs WebGL, which most current browsers offer. Update your browser, turn on hardware acceleration, or try another device. The 2D drawing shows the same machine meanwhile.
