I have been unable to authorise my Adobe ID in Overdrive for several days. This means I can't read/borrow titles from my local library. I chatted with an Adobe rep 3 days ago & was promised this problem would be fixed by now but it hasn't been fixed. Can you please help? I'm using an iPad with iOS 10.0.2 installed. I can sign in to the Adobe website so I know my username & p/w are correct.
