Yes, to my understanding this should be possible. Are you sure that you have the latest version of nrfgo studio? You should try downloading the latest version from here.

Yes, there is a difference. It is true there is no pinout difference for the three revisions. But there are differences internally. For example newer SDKs won't work on old revisions and it may be true vice versa (older SDKs don't work on newer revisions out of the box? really not sure here). Anyways look at the whitepaper Fredrik linked to above. Also you need to make sure that the softdevice you are using will work on the revision of the chip you have. Another thing: the amount of memory you have (FLASH and RAM) may change so make sure your project settings in keil or linker file in GCC are correct for the revision.

Just know that things change when switching revisions. The link Fredrik posted should solve the problem.

Hello, there is no change in the pinout in the three revisions. Are you sure that your connections are good?

Here you can find white papers explaining how to migrate from revision 1->2 and from 2->3. They might be helpfull.
