#linkedin shares insight returning 'Not enough permissions' error, 'status 403'

Trying to get additional information for a share ( share->activity ) via shares API v2 getting the following error:

Call

'https://api.linkedin.com/v2/shares/urn:li:share:67953.......'

Response

'message' => 'com.linkedin.content.common.ResponseException: com.linkedin.restli.server.RestLiServiceException [HTTP Status:403]: com.linkedin.content.common.ResponseException: Not enough permissions to access urn:li:share:67953.......', 'status' => 403,

Inspecting the token leads to this:

• token is 'active'
• granted permissions
  • r_liteprofile,
  • r_organization_social,
  • rw_organization_admin,
  • w_member_social,
  • w_organization_social

Our code worked before this strange error occurs.

Thank you for your help in advance.

Best regards,

Andreas
