If you are in contact with the UBports developers then can you ask them to get in touch directly via an existing Purism contact? If you are a UBports developer then can you talk to your colleagues and find out what the status is from their perspectives?
My impression is that there are a very small number of development boards, but that most of them are already assigned to third party development groups. For some of those groups, the task of assigning the boards was left to the people in charge of those groups and I don’t know whether there was clarity about who should receive boards.
