QuickBooks mobile app updated and now when I create an estimate non of my customers past the letter C show up. On customers page they still exist just not in estimates

Good day, @hotpointslightin. 

We received similar cases about the latency displaying customers. However, I appreciate you for performing some troubleshooting steps to fix it.

In the meantime, you can restart your device since you're done trying to uninstall and reinstall the app after updating. This applies to both Android and iOS devices. It will refresh your phone operating system and fix some latency issues.

You can read this article for more info: Fix common errors in the QuickBooks Online mobile app for Android.

Moreover, if you wish to get updated on the recent cases of customers not showing in the estimate, I recommend contacting the QuickBooks Online (QBO) Mobile App Care Team. They can add you to the affected users list.
