Did you buy this Play+ new?
Yes, I bought it new and it does register on Polyend’s site as a Play+
I’ve searched through the forum and it seems that I have the same issue as described here:
Try to delete your workspace folder on the sd card and retry. Sometimes it gets corrupted and that is a fix that works for many things.
I tried it but it doesn’t fix this issue. Anyway thanks for an advice!
I think it’s really just a matter of a manufacturing trouble, so hopefully I can change it for another one, but with the right firmware.
