I set up the Los Angeles time ( the only available for California), But it shows the wrong time, a 3-hour difference. For example, it shows 10 am when in LA it's 7 am.

I tried to upload some powerpoint presentations from my OneDrive but they are not visible here in Liveworksheet. Whenever I try to upload them, the phrase "This element cannot be loaded now" or "this request is blocked". How can I solve this? 

Please I need an answer.

I'll attach pictures
