cant find the contact button
Do you mean relationship viewing if so here is a link to the discussion forum on this -> https://tech.churchofjesuschrist.org/forum/viewtopic.php?t=34956#:~:text=Re: Requests to enable relationship viewing,-Tue Jan 21&text=If you're reading the,"Enable Relationship Viewing" selection.
There are two ways that I know of to "Enable" the "Relationship Viewing":
One is through your "Settings", under the "Permissions" 'Tab', in "FamilySearch".
The other is when you select the "Contact Name" of a User/Patron who has contributed details to a record.
Here is a "Knowledge Article" in 'FamilySearch'
How do I turn on or off the option to view my relationship to other users?
I hope this helps.
