Jupiter's UPI went bad

Few months mack Jupiter UPI was very fast in merchant payments (Via QR code payment). As this was very convincing I started using it regularly (daily to go app).

Now a days ( past 1 month) its UPI is very slow(not network issue). Literally It makes me feel pissed off. very worst experience than other payments.
[ After scanning UPI code app is dead, no response all of sudden I have to close app and open again. I will try again doing the same steps- this is in loop]

Now my merchant payment are done through other UPI.

Please fix it, otherwise I will close my Jupiter account @Jiten
