BritBox not loading and no useful support

BritBox is not functioning. At the end of December 2021 I bought a year's subscription and until recently (one week ago) I could watch the few really interesting and new shows that attracted me. BUT over the last week all I can get is a screen that shows that the App is connecting/downloading and nothing else. I have tried to use the BritBox helps lines but no help there at all! I know of several other people who have the same problem. At the present level of usefulness BritBox is a monumental waste of money unless this issue is resolved ASAP.
