Lock option is not showing in powerpoint

[um_m4]

It is not there in selection pane of powerpoint.

I'm using the latest version

Also, not there in context menu. 

I have reinstalled it several time, also with the microsoft support and recovery assisstant. I have a newly installed windows, and before that it was working fine. This tool is in my usual use, so I cannot be more efficient without it. Currently I'm using office online as a replacement. I have also checked 'All Commands' of ribbon option, and it is nowhere - also searched it in bar (ALT+Q).

You just need to join the insider program

I'm facing this issue too - was this feature removed in the latest version?

Yeah, I'm also wondering. Removing that doesn't make sense, as this feature is in my daily use. It's been a month and still they didn't fix it.

Insider program fixed the issue. Thanks.

That would be great! But sadly my account does not provide an option for joining the insider program, even though I have a full 365 subscription
