MYOB Invoice APP

We are a smallish business that receives 20-30 payments a month. We have used the MYOB Invoice app since it first came out and it always worked well.  A few months ago they made an update to the MYOB Invoice app and now it no longer works the same way.  The invoices used to be marked off as paid offsite and when I would do the reconciliation those paid invoices would appear for me to check off.  No problem.  Easy.  Now they no longer appear in my reconciliation screen.  After numerous discussionswith MYOB we worked out a workaround which meant a longer process for me having to login to get bank feeds etc and mark them off.  Did it for about a month and then found out that the invoices were actually being duplicated in the system, once when they were marked as paid on site and then because I was marking them as paid through the bank feed. So when I went to reconcile I had two of each paid invoice.  The invoices I was marking off in the office was being sent for some reason through to Undeposited Funds - so my balance was correct at reconciliation but it of course affected my BAS dramatically.  The Undeposited Funds were showing up in the Balance Sheet and my accountant asked me about them.  So yesterday I spent 3 hours on the phone to Myob and couldn't work it out.  They then told me to try MYOB Assist as MYOB Invoice is being discontinued in November 2025!  No heads up at all!   I have downloaded MYOB Assist and entered a test invoice - 1) it did come over to the web browser version - however when you press the "send" button - it doesn't give you any indication that it has actually sent and 2) when I went back to view my one and only invoice it says "unable to load invoices- wait a moment and try again" - what a joke.  I am going to make the move to Xero I think - I have done a free trial and everything I am trying to do has been done with no issues.  Good app on the mobile devices and seems as it should be.  I have given MYOB every opportunity to help me through this and this particular 3rd party providers are rubbish or they are now - they used to be sufficient to do the job.  Most of the other accounting software I have looked at - the syncing between 3rd party and web browser is standard.   I have been with MYOB for 20 odd years so do not take this move lightly - will be a big learning curve and setup all over again.
