I think the trp format has changed over the years because none of the rival shows are doing well either. EBSS was different , trp audience is acquainted with the sanskari bahu concept whereas janhvi was grey , the youth gen cannot watch shows telecasted at 7pm but they have given their verdict through online trps which is satisfactory.
But EBSS could do better , it did fetch 1.3 (?) trp in the first week/day.
The writing was not it tbh , they rushed with every plot especially kabir kavya vyom plot ( even though I am enjoying kabir kavya scenes rn and I would really want kavya back in the show ) and ofcourse ! janhvi-manohar's plot made no sense towards the end.
Time slot is a problem but it's not the only one.
