Hello all,
I am having the same issue here, after reading some of the replies here, I am wondering if this issue pertain's to Microsoft's end.
Situation: Did a test schedule poll between my account and a test account I stood up. Selected the times and poll is sent out. Test account received it but when click on "Vote", it will open up a new tab and display a spinning/loading animation to no avail.
For context, this test has been done strictly between OWA and through multiple browsers (Chrome, Edge, FireFox) default and incognito modes, as well as different OS (Mac & Win, though it may not matter)
Could a Microsoft Tech/Rep please look into this issue? Thank you!
