Ola Money — Unable to use Ola postpaid on Zomato

I am a very frequent user of Ola Postpaid + and I do hold limit value of 12k. I am unable to use the Postpaid plus feature on the Zomato app recently. Previously, I have regularly made payments through Ola money postpaid, but recently the option has entirely disappeared and I cannot add it back.

Please look into this and let me know because i have always paid my dues on or before time and hold good credit score as well.
