Whatever is previously paired works, but new devices fail to pair. If I reboot into kernel 5.4, I can add new devices, then boot back on 5.8 and they will work. It has been like that in all 5.8 versions.
As I understand, 5.8 is a major release, with the largest number of commits in a long time. It is worrying to see such an important release breaking important stuff.
