Ok so after my first glowing review, I have run into a significant problem with the app. I recently purchased a Samsung S21 phone. After the last software update, I can no longer get a full-page view of my writings. In response, IM says, "Sorry, we're working on it." Apparently, it is an issue with Samsung compatibility. No other explanation, just the obvious "try re-signing in"... Stay tuned.

I'm having the same issue with this glitch. Once I open or start up a new invoice it freezes and or stops all functions. I love this app, but it's hindering on work flow. Will this be fixed? ** as I was checking it out more. As I write and invoice/estimate the Grammer fixing function withing the keyboard which looks new option starts to freeze the app and or makes it glitch. If the Grammer function is not recognize any errors, it seems the app is fine ** don't know if this will help fix issues.

I like this app so far, but I have one issue in that for some odd reason when I add a new customer I shows the invoices with another customer associated with that one. Additionally, it would be great if it were possible to make notes on the invoice that did not have to be shared with the customer. Also, since the app uses online payments through PayPal, and PayPal charges a fee, as the business owner I should be able to pass that fee on to the customer is I so choose.
