Is the investigation you mentioned for Safari on iPad or Safari on Mac? 

According to https://quickbooks.intuit.com/learn-support/global/getting-started/quickbooks-online-access-for-mobi... is not supported for iPhone or iPad - just Safari...but the reality is that Safari really isn’t supported either. 

I prefer Chrome, but will use Safari if that is what works best. Just need a solution and fast. I cannot run my business!

a) print an invoice
b) change invoice template

Customer Service told me these are not bugs, rather, simply “not supported” at present and I should submit a feature request.  If not supported, don't display these features.

All of these are basic functions of using QBO, but they do not work on iPad.
