We just received confirmation from FamilySearch that they turned off the temple card endpoint on Jan 15th. This was their official date but we were never aware of an actual date it would happen. In the next update the Temple Work icon on the FamilySearch Central Dashboard will be removed. We cannot implement any changes in that area because there is nothing that will feed it.
If you are still able to open the Temple Work section and see any information there, it is old data and will not update.
The only area you can see temple ordinances and make reservations in RootsMagic is under the FamilySearch Person Tools on the Ordinance tab. All other temple work activity needs to be made on FamilySearch.org under Temple.
