I use the @ecency -app on my iPhone. A few days ago, I had problems logging in. Somehow, it worked eventually. But since then, I've been getting the message shown in the picture. When I click on Cancel, I can use the app normally. I've already uninstalled and reinstalled the app, but without success. Yesterday evening, after reading your post, I checked to see if there was a new version in the App Store. And yes, there was. However, this did not solve my problem. The message still appears.
