I have 2 different accounts. On both as of last night, I'm unable to follow anyone. When I click follow it changes to "following" turning the button green, then loads and goes back to "follow". I know that Instagram only let's you follow a little over a total of 7, 500 people and only a certain number every hour but I only follow 34 on one account and 400 on the other and I haven't been able to follow since last night. I'm also able to follow online on webstagram so it's not like I have been banned from following people. I figure something is wrong with my accounts and instagram app connection. I have tried everything to try to fix it. Restarted and restored my iPhone, redownloaded instagram (updated) and logged in and out several times. It doesn't make sense. Especially because I have the same problem with both instagram accounts. Any ideas to fix this?
