I literally pay for adobe acrobat monthly and have the latest version of acrobat reader on my phone. So, when I attempt to download and view my billing statement as a PDF, why does the ameren app give me a message that says I don't have an app that supports viewing that kind of a document? Yes, I do. This ameren app is a joke. It's not user-friendly at all. It exists to serve one purpose, take our money. If I didn't have to have ameren as my energy provider, I wouldn't. Do better.
