# Vector notation issue in iOS application

Everyone's answers and questions is displaying vectors very weird. For example \vec F gives:

$$\vec F$$

What happened? How can we fix this? I hope I don't have to redo my past answers...

• Could you include a screenshot to show how it is displayed to you? Have you tried what happens if you change Math Renderer in MathJax menu? – Martin Sleziak Jul 22 '17 at 7:38
• I have added a screenshot, I don't know how to do that @MartinSleziak – Ahmed S. Attaalla Jul 22 '17 at 7:40
• This is what I see in your post here on meta: i.stack.imgur.com/0Trrf.png – Martin Sleziak Jul 22 '17 at 7:41
• Hmm weird, perhaps it is because I am on iOS. – Ahmed S. Attaalla Jul 22 '17 at 7:42
• To see how math renderer can be changes, see the screenshots in this answer or this answer. However, I do not know whether this works on mobile devices. – Martin Sleziak Jul 22 '17 at 7:44
• If it turns out that this is problem with mobile web or Stack Exchange app, probably the relevant tags should be added - namely (ios-app) and/or (mobile-web). – Martin Sleziak Jul 22 '17 at 7:45
• Maybe it's time to switch to Android based devices. – Asaf Karagila Jul 22 '17 at 8:37
• This is due to a regression in Safari 10. The upcoming 2.7.2 release will include a workaround. – Peter Krautzberger Jul 22 '17 at 8:59
• @Peter: Safari? You make it sound like it's a real jungle out there! :P – Asaf Karagila Jul 22 '17 at 10:34

• Just thought I should add, I experience this issue on an IOS device as well. – Dando18 Jul 23 '17 at 21:24
