47uF VDD decoupling capacitor on nRF52810-CAAA (WLCSP package, C9 in reference schematic)

  We have a customer whose product uses nRF52810-CAAA,It works on Bluetooth and the transmit power is 4dBm. And they added a 47uf capacitor to ground on the VDD side of the chip instead of the 4.7uf value recommended in our datasheet. Does this have an impact on chip operation? At present, the products they ship have a certain percentage of complaints, Bluetooth work is unstable, and we suspect 47uf. Due to the low power consumption of this product, using ultra-small coin cell batteries, they need to use 47uf capacitors to ensure the power output of the power supply.

  We found a similar issue in devzone as below, please help confirm it? Thank!
