You are on your Display.Church Integrations page.
You notice that it says "Session expired. Re-authenticate"
No problem. Here's how.
Step 1: Click on the turquoise Re-authenticate link (see image above).
Step 2: The page will refresh to remind you what you are planning to do.
Click on the turquoise Re-authenticate (gold box in image above).
Step 3: The process should happen automatically and be confirmed. The confirmation message will differ depending on the integration you are re-authentication. Here is an example below:
Click on GO TO INTEGRATIONS PAGE or whatever return option is given.
Step 4: The page will refresh to your Integrations page.
Note that now your Integration has been reactivated and is re-syncing (example in image above).
