Hi Kal_Lam. I’m also having trouble adding permissions. I have 14 users in the project, and the user already has access to another project, so I know the username is correct. We are on the “kf” instance. Thanks for checking on this for all of us!

@volunteer , @kh1 , @hm11 , please be informed that this was an issue at our end, which has now been resolved. The sharing permissions should now work smoothly. Thank you once again for bringing this issue to our attention!
