Missing child sheet in xls exports

starting from Oct. 4, 2021, all xls exports either got failed or exported BUT without the Child sheet!
plz advice.

Welcome back tot he community, @ismailhammad! So you mean you are not able to download the repeat groups? Could you confirm?

thanks @Kal_Lam for your prompt response!
yes, it downloads the parent sheet only, without its repeat “Child” sheet.

@ismailhammad, could you also share with us a screenshot so that we could also understand your issue pictorially?
