"we don't have an exact timeline when it'll be fixed"
That doesn't sound to me like it's a very high priority and doesn't inspire me with confidence that it will be fixed given that I've been told that it's been fixed multiple times before (when it clearly hasn't) and the tickets has been closed with checking with me to see if my issue had actually been resolved.
In that case I will continue manually checking and adding the missing transactions and will continue invoicing for the hours of my time that this is taking. Perhaps you can also remind your accounts team that the two invoices that I have submitted via QBO are now overdue and that reminders have been sent ? I will be invoicing for the hours that I have wasted doing manually what QBO used to do automatically until this is resolved.
