Netflix and Dstv Stream no longer working on SANSUI Tvs

For some funny reason Netflix and Dstv stream is not working on sansui...i have 2 Tvs both sansui smart tvs and both of them want me to update software or device. When I check on settings, both tvs are on current software version and I can't get anyone to assist me with this. Word of advice, DON'T BUY SANSUI PRODUCTS, rather buy tvs with funny names if u can't afford proper brands coz wow
