How to restore acces to restricted pages in imported page?

[Anton Hapieiev]

Hey there! 

For company needs, we're in the progress of moving from Server Wiki to Cloud Wiki solution. While export/import of spaces I've faced the following case: 

1. I've imported space existing in Server Wiki as .zip file to Cloud Wiki. That space has restricted pages with certain users allowed to view/edit those pages. 

2. It seems like those restrictions inherited to imported space as well. But because those granted users aren't inherited any current user cannot get access to such pages. Her's what I've got trying to open such a page - https://prnt.sc/tag9hi. 

3. I've tried Recover Permissions - it doesn't help. 

4. When in Space Settings / Permissions / Restricted Pages I'm trying managing one of the restricted pages I'm also getting such screen with no access - https://prnt.sc/tag9hi. If I'm trying managing Former user permission here's what I see - https://prnt.sc/tagesr

Please advise how to at least restore permissions to somebody from current Cloud users so that we'd be able to reproduce remaining permissions from scratch.
