I lost the developer signing keys for the playbook in a hard drive crash. I tried applying for new keys, but have not got a reply back. Tried to mail them too but no reply. Is there a way to get signing keys in 2020 for the playbook? I believe Blackberry team monitors stackoverflow for legacy support.. Hope they can help me.
