Share Rights

Hello to the Zoho Show team!
Just a quick question if I may?? Actually 2
1. We have someone that although we have deleted and re-shared a presentation with her over and over she doesn't get the veiw/edit rights. This prevents her from being able to conduct remote presentation. There are embedded links to images in the pages of the presentation if that may help with your understanding.
2. Is there any way we can lock our presentation so that after we have shared it the receiver cannot share it further? The presentation is working very well and we don't want to have it shared elsewhere.
