Did you install the app from the /e/ App Store? I installed the app from the Aurora store (you will soon enough here about other options of app stores).

Please take notice when using Aurora store, that you should care which app is to be updated. It has been discussed in the forum often times. For example here: Aurora Store - Google Play Services Update
Hope it clears some things up, if not, keep asking
