Instagram has not made a native app for Blackberry 10 and the new Z10 smartphone. The only way you can install this app on your device is if your sideload the Android port. One of the big problems with this app is being able login properly and not getting “Cannot process request, please try again shortly” or “This app requires an update from Google Play.”
The first thing you want to do is link your Facebook account to your Instagram account. You can do this on the iOS or Android version of Instagram. The next thing you want to do is fire up Instagram on your Z10 and instead of logging in, you want to click on forget password. You then want to select “Forget using Password” using Facebook. You will then be prompted to create a new Facebook password. Once you do this, you will automatically be able to start using Instagram, take photos, and use the app.
One of the most consistent issues you might encounter is “cannot process request, please try again shortly.” If you have a Facebook Page, or are the administrator of one, the app throws you this error. The best solution is not to have a Page, or you can’t use the app.
