Think I solved the issue after WGT responded after sending screenshots of my game etc.
I bought credits early morning before went to work on the 3rd (UK) time, Even the transactions from my bank buying credits are on the 3rd (UK) but in the game credits spent says the 2nd. So guessing WGT golf is American & we are in front of you time wise. They said the promotion started on the 3rd in an email.
If I would of just played the game like on my usual break time at work a few hours later & spent all those credits would be entitled as would of been the 3rd in USA too.
Thanks for the responses. When I played the game on my lunch break that day & seen the tap in rewards was wondering why nothing was unlocked for it but guess I just missed out on it being on UK time.
Thanks for the replies
