An update for the iPad version of HomeRoutines was released to the store yesterday, fixing a crashing bug. Unfortunately, we managed to introduce a new bug while fixing the old one.
Due to this bug, if you open HomeRoutines for iPad in portrait orientation, the Home button won’t be visible. Fortunately, if you rotate your iPad to landscape, the Home button will reappear, and will stay there after you rotate back to portrait.
We have also submitted an urgent update to Apple to fix this, and it should be available within a couple of days.
