This is an awesome app, easy to use, great looking invoices, but it isn't accessible. After using my 3 free invoices it asks you to subscribe. After many HOURS of conversations, rebooting, reinstalling & many conversations I realised I was on my own. After confirming the transaction with my bank, the app would not allow me access to continue. The only way i could clear the glitch was to reboot my phone and at that point lose the transaction. ☹️
