There is no point in asking users to contact customer support or clearing the cache.  The problem is on QBO's end.   

It was working fine until recently - user could click on 'receive payment', process the payment and click the default 'save & close' button on the bottom right.  The default button is now 'save & new'.  Its very simple, something changed on Intuit's end.  

Please dont waste users' time suggesting customer service calls or clearing cache. 

Instead - contact the group within intuit that made the changes, ask them to fix it,  and then report back to us and let us know if it is going to be fixed or not.  Please report back asap with an update on what you have found.
