No I did not solve the day problem, unfortunately…
I actually needed mainly to switch between week and month view, and The only work around that worked for me has been to use to calendars on the same page, one hiding the other, and display the one with buttons… If the plugin worked I had been happy to let users the choice of a day view
Hopefully @seanhoots will release a new premium plugin soon, we are all waiting for him to save us!
