Hello farrahleigh11,
Just to clarify, do you only experience this issue with that specific app? If you're experiencing an issue with the Instagram app, we'd suggest reaching out to the app developer, so they can check into this with you and assist.
If you need help contacting the app developer, please check out this link, which has some helpful information: How to contact an app developer
When to contact an app developer for help
* If an app isn't working, but the issue doesn't affect other apps
* If you can't use an in-app purchase, such as a bonus game level or "remove ads"
Contact the developer of an iOS, iPadOS, or watchOS app
1. Open the App Store on your iPhone or iPad.
2. Search for the app, then tap it. If you can't find it, tap the account button
or your photo at the top of the screen, tap Purchased, tap "Not on this [device]," then tap the app.
3. The app's product page appears. Scroll to the Ratings & Reviews section, then tap App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID.

Thanks!
