Hi,
The yellow triangle warning message is displayed by Google Play and does not hang with our app directly.
Version 6.94.2 was not pulled from the Google Play Store. It takes time before the new version is available to 100% of all users.
The first scan with 6.94.2 might have been slow due to something specific on your device, e.g. number of installed apps, files, etc. If you notice a slow scan again, please let us know, and we can look into it.
