Rev 3 of nRF52840 have improved APPROTECT mechanism. The introduction of that and how it influence your application development is given clearly here in the blog. Please make sure that the changes necessary are included in your app. Other than that, I do not see why BLE does not work as rest should be same

I tested ble_app_blinky using nrf5_sdk_17.1.0_ddde560 on rev3 and it works fine

Only the above message appears in the rtt log window
There are no errors
There is no difference between revision1 and revision3 boards
There is no difference in the source
Just ble does not work
Are there any changes in revision3?
I also updated mdk

It is really hard to say what went wrong. If you have some logs on the serial or RTT then we can get some more context of what failed. If the device is powered at all?
