Address search not working in Collector

[AlexWarner]

Any address we type into the address search comes back with no result. Is anyone else having this issue this morning? Everything was working fine yesterday.

We are using the Collector Classic. 

*I made this post earlier today, but accidentally marked it answered. This issue has not yet been resolved. Attachment shows comments from old post.

Alex Warner‌ the geocoder Collector uses is defined in your ArcGIS organization's settings. See Configure utility services—ArcGIS Online Help | Documentation for more info. If you are still seeing issues getting addresses returned, you may want to confirm that this hasn't changed recently.
