I changed to the new plugin recently - many of my games have had billing before, and even though very few purchases, I haven’t seen a problem.
Now I am getting every purchase that is not consumable being refunded in 3 days. I thought I was unlucky but it kept happening so I looked into it - it seems the purchase needs to be acknowledged.
I use; store.finishTransaction(event.transaction) to do this - I thought this was what I was supposed to do???
Can’t see any problem - does this actually work?
