Get the app on your phone
Tap Settings in the message and turn on Allow from this source for the app you used to download the file (usually Chrome or Files). Go back and tap Install again. If you do not get the button: Settings โ Apps โ Special app access โ Install unknown apps (Samsung: Settings โ Apps โ โฎ โ Special access).
The app is downloaded directly from us and is not in Google Play, so Android may warn you. Tap More details โ Install anyway (or Scan app, then Install). The app is published by Expeto/Lytzen.
Small fixes arrive by themselves when you open the app. When there is a new version of the app itself, a banner appears in the app โ tap it, download the new APK here and install it over the old one. You do not need to uninstall first, and you keep your login.
Delete the old APK in Files/Downloads and download again. Use Chrome (not an in-app browser), and check your storage and connection.
The app needs Android 8 or newer. Also update "Android System WebView" and Chrome in Google Play if drawings or 360 images do not show.
The app requires a login with your OPPKAS account.
