What can You do After Instagram not Working on iPhone?

Firstly, delete the crashing Instagram++ first.

Secondly, re-download Instagram++ from Panda Helper. If your Panda Helper crashed, delete it first and re-download Panda Helper from the official website.

Thirdly, you can re-download Panda Helper Free version or upgrade to Panda Helper VIP with a more stable year card.
Re-download Free Version: If the official website displays the status, Panda Helper Free version can be downloaded. It means the Panda Helper app has been re-signed and can be re-download now! Click the “Free Version” button, and download it.

Download VIP Version: Click”VIP Version” to download Panda Helper VIP.

Afterward, follow the prompts to install the panda helper profile so that Panda Helper installs successfully. Please wait for it to install on your home screen.

You can go to Settings > General > Profiles & Device Management > Downloaded Profiles to trust a certificate used by Panda Helper. (Since apps need the certificate from Apple and can operate on iOS devices, we need to trust the certificate to get used.)

Fourthly, open the Panda Helper app and enter “Instagram++” in the search bar.

Lastly, you can get all results in Panda Helper. Tap the app you want, and press “Download” to start downloading. A pop-up will appear after downloading to tell you to install the app when you open it the first time if you see the “Untrusted Enterprise Developer” message. Go to the Settings app,> General > Profiles & Device Management, and trust the app’s profile. Check out Instagram++ and have fun with it.

Apps in Panda Helper will be resigned one by one. Please be patient and you will get all of them without jailbreak. Redownloading the app won’t take long and it is a definitive solution while apps are crashing, though it is annoying.
