Can’t log in anymore – iStory for Instagram Review

Past few days I can’t log in anymore. If I sign in, an instagram prompt comes up that calls it “suspicious login attempt”. It prompts to send to send security code to email, but even after clicking it several times..it still doesn’t send a security code to my email. I even checked the junk mail. They don’t send any code. I tried on my separate instagram blog account and it says the same thing. Please advise what to do. I will change rating and review immediately upon developer response. Please look into it. Thank you.
