"Instagram could not be downloaded at this time. No matter how I try I am not able to download the app. Pls Help

So I currently have an iPad 3 and I download Instagram regularly using the iPhone only option option in the AppStore. I've downloaded it many times before but this time I keep getting the same message over and over (Other apps I have been able to install as usual it's just this one) I've tried a VPN,I've tried a reboot, I've tried changing the date/time If there are any solutions to this please do help.
