I granted permission to an account, but the permission disappears after first login

First of all, there is an account never login the sharepoint site.
And I granted this account the permission to an item in a list
image

However, this read permission will disappear after the account first login to my site.


Please help to fix. Is that a bug on sharepoint?

Hello @itapps,

You need to contact MS support on the matter or you can try granting access to the SharePoint Item using Plumsail Actions. You can find the instructions here:
