Q: Updating Instagram app and it's been stuck saying "Waiting..."

Hello iansiah,

Thanks for asking your question here in the Apple Support Communities. Seems that there is an issue updating an app. I'm happy to offer some help with this.

The first thing we want to ensure is that all your data is safe. You can make a backup in iCloud or iTunes. Use this article for help with that: How to back up your iPhone, iPad, and iPod touch.

This issue happens for a few different reasons. I have personally experienced this when my iPhone did not have enough space to handle the updates. If your iPhone only has less than 1 GB of space left, you may want to make some room using these two articles:

1. Check your storage on your iPhone, iPad, and iPod touch

2. If you need more space for an iOS update

If you have plenty, or made lots of space and still have the issue, please try turning your iPhone off, then back on again. Sometimes, that is all that is necessary to get all the connections reset and everything working properly again. This help article will assist you to do that: Restart your iPhone, iPad, or iPod touch. Please do not do the force reset, as that is not necessary at this time, and your device is not exhibiting those symptoms. 

If you still have issues after the restart, please check this help article: If an app you installed unexpectedly quits, stops responding, or won’t open.

Thanks again and have a great rest of your day.
