Disappointed

I bought a Hisense Smart TV in 2021, its been working perfectly. So recently i paid for Showmax and when i try to stream on the television it gives me a message which says they are busy liaising with the Showmax team for compatiblity something, OK fine. I then lodged a call with the Hisense team to which i got a response a ticket number and later received another response requesting the model number from a lady named Abigail and i send that and then the next response was that, We apologize for the inconvenience, please note that due to hardware limitations, the unit does not meet the minimum hardware requirements for the new application, therefore you will not be able to stream Showmax We recommend exploring alternative streaming methods such as getting a smart/android box that is compatible with your TV by visiting an Electronics store for assistance

What kind of a smart TV is it that is not compatible to apps like Showmax and needs support from smart/android boxes?
