p.s. – this suggests it just takes time for the refund to be updated

But I’m not convinced – I realise they’re caching purchase data on the device but 24h is a long time…
Updated to add that more than 24 hours after I cancelled ‘test’ transactions, those accounts are still licensed!!
Updated again – after 36 hours the app was STILL licensed. I uninstalled and reinstalled and it was STILL licensed!!
Updated AGAIN! – I factory-reset the device, logged-in, installed the app and it was unlicensed…
AND another update – a reply from Google suggests that refunds are processed ‘automatically’ but can take ‘upto 72 hours’ to be refreshed on the device – there is no other route to detect a refund, so players get upto 3 days of stuff ‘for free’ if they refund – erm, OK this is In-App and not App purchase but still, that seems a BIT excessive?
