I have a simple e-commerce conversion tracking going, all working fine .. until ..
I was looking at a report, and clearly saw 33 transactions .. its a completely unfiltered stat from a simple clean property. however a few minutes later i looked at the same report and it was down to 31.
33 was right, as per verified with another system , .. why would GA 'delete' a transaction like this ? , i have no code anywhere that would reverse it. ?
There is a delay and post processing in GA that can take up to 48 hours. In most cases it takes a few hours until you see the final data in the reports. https://support.google.com/analytics/answer/1070983?hl=en#DataProcessingLatency
Hope this helps.
