30 minute increments in scheduler?

[Toni18]

Hi all,

My scheduler link shows my availability but only on the hour - there is no 30 minute increments.

Yet, watching a YouTube video that guy had it.

Is this some setting or something? 

I know I can use 15 and 30 minute increments when creating a meeting, but visiting my schedule link doesn't.

(Hope this makes sense) 

Thanks
