BAS Taking Long Time To Prefill

I'm having the same problem.  I have to leave it open for 10 min or go and come back a few times.  This is not going to work when I need to get a lot finalised in one day.  I'm also finding having to individual step thru 3 or 4 approval checks and then individually lodge is taking a long time.  Old system I could just have them all sitting their and lodge in one go.  I find it hard to even seach on if the lodgement was succesful as it doesn't allow you to put in order of what was just lodged.  The date order is the due date of the item and you might be lodging BAS for different periods.   I'm convinced I'm missing something here as it is going to take  a lot longer to do the process.  Surely they would not want to increase our work load
