Signed up for year subscription on 26 sept 2018 could not get app to work on samsung 4k tv, emailed Acorn on 27th and again on the 28th no reply so assuming they must all be on holiday lol and asked them how to get the app working. Thenon sept 28th 2018 noticed as of the 27th samsung no longer recognises the acorn app. Did samsung just say that the morning of the 27th and was it a surprise to Acorn? On the Acorn web site said that you can get Acorn Tv through Amazon Prime but no instructions how to do it. Seems they dont care they got my years subscription money so now have to try to get it back.
