Hey TechnoJoe -
Yes that is the case at the moment (UK players are set at the lower RTP for Red Tiger and Play N Go), outside the UK it is just over 94%. We didn't have these providers prior to the migration which took place on the 20th November, so this is the first time we are offering the content.
Unfortunately, the way Aspire's platform currently operates, they make the decision on local RTP's and the network all use the same setting. However they will be implementing the ability to split RTP at a brand level next year, at which point we will thankfully have the ability to make our own decision. All other slots are set at the standard RTP's for all markets.
I'm really sorry to hear this created a bad experience for you, we will be improving the RTP on that content as soon as we have the ability to do so. I don't have an exact date yet but I'm hoping to get the full road-map in the coming weeks. Please feel free to PM me if you have any questions and I'll be happy to help.
Thanks,
Rachel.
