I've created an Excel Survey on my Office 365 account and shared with students & staff to complete.

The students are all using Macs running OS X 10.10 or 10.11 which has Safari setup as the default browser.

On Safari the students are NOT directed to the Thankyou page which says "Thanks! Your response was received"; after they 'Submit' their survey results. Now I can see that their survey results are coming through in the Excel worksheet. Consequently there is a lot of confusion amongst students as they don't know whether their survey results have been submitted or not.

Anybody aware of what is going on with Safari?

The best workaround I could come up with was to have students use Firefox to complete their survey as that DOES redirect students to the Thankyou page upon completion.
