Nice little app but,

At first I really enjoyed using this app, however after using it for 3 months I decided to save a backup of some 60 invoices that I had created using the full version. Then I had a system failure and upon trying to restore the data from my backup, I was disappointed to find less than half my data had been saved. Upon contacting the support department to inquire why this had happened, their only response was "Moon Invoice Pro is free version with limited usage.
And if you want to have full access of app then you need to upgrade app as a full version.” I have the full version plus the other admins, so their response was not helpful. Meanwhile, I have to go back and restore all the invoices and data manually.
