Is there any 1.8v power related issues with nrf52832?

We are developing an nRF52832-based circuit with 1.8v power supply, which features BLE, NFC, SAADC, I2C & SPI.

According to datasheets, all 3rd party components are also 1.8v compliant.

We have already produced a dozen of test PCA samples that work completely fine, but factory has issues with chip programming (via SWD), and says of "riscs of chip instability" with that power voltage.

Is 1.8v powered circuit design reliable in mass production with nrf52832?

Notice on any known issues would be absolutely helpful.

Thanks.
