We have a firestick someone where my son used to work added on stuff for us and gave us instructions on how to access the latest films etc, whilst new releases werent the best quality they were watchable, recently though nothing seems to load, we get the same message come up " no stream available".would this be something Bulent could help with does anyone know please, like would it be possible to wipe everything off and start from beginning again? We are not very techy...
