Just did the upgrade and no scan manager is horrific!  I work from my desktop, not my phone!  I now have to scan to files on my computer and go in and out of QB if I need to find the paper trail.  The mobile app would be fine for a receipt here or there but not for attaching contracts or service acknowledgements or bank statements.  Who wants to name and number each individual page?  Not me!  Thanks Intuit for making our jobs more time consuming!
