There was an error recognizing the MKR1000 as adafruit circuit playground express. How do I fix it?
Really need a bit more information.
IDE etc etc etc. ?
Not seen this issue before either so wonder if you manually selected that adafruit ?
You could try to manually select the MKR but also check (in windows) that the MKR is showing up in device manager as an MKR.
btw posting duplicates does not help your issue as its wastes peoples time and effort. Try to avoid that in the future.
