Many Instagram users do not have comments, but still more people can’t sign up person: you click on the subscribe button, it lights up in green color, and then almost immediately reset to the original the value is not signed. What to do?
I want to upset you a little: to do nothing in this situation you can. This is a glitch of the Instagram application. And I had it, I just waited a while, and he himself passed. But I can give you a couple of tips.
The first thing I can advise you: update application on a mobile device. It is possible after updates you can subscribe to all interesting you users.
My second advice is also very simple: go to your Instagram account from a computer using any browser, go to the page of the person you want to read, and subscribe to it. From a computer, everything should work out for you!
