I have been watching Game of Thrones starting with season one over the last couple of weeks on HBO's on demand and was half way through season 4 when the previous seven seasons suddenly were no longer available. The only season now available is season 8. This is extremely frustrating and I hope you can rectify this situation. I have thoroughly enjoyed watching this series and hope you will add the previous seasons back to on demand immediately. I am sure there are many others like me who have not caught up with the series yet. Sincerely, Chris Willis
