Minor fixes

User reviews

Nowhere near as good as it used to be

Why am I having to delete and reinstall this app pretty much weekly because it freezes/ goes completely blank/ doesn’t update?

App crashes

The latest version of the app crashes constantly and won’t actually open at all.

Still needs support for landscape mode

Had confirmation from Leon that this would be incorporated but seems like absolutely no effort to incorporate such a simple yet necessary feature. Terrible app

Portrait to Landscape

Still waiting for a flippable version. Ultra annoyed having to rotate the ipad every frickn time whenever I need the app.

Unable to enter data to the journey log

I have been unable to enter any data into the journey log for about 2 weeks. The app has some useful features, but none of the useful bits are available unless the is connected to the server via 4G or wifi-broadband.
