That is very new and i do not see imports from Bug Reports - Sailfish OS Forum plus that category being closed for good.
Github is a very good choice to start over (IMHO), but i also guess there will be the typical complaints (this is MS and i need an account).
The really interesting part is what Jolla actually uses when they call things “tracked” or “#JBxxx” (or whatever it is). Also those are not imported in github.
So cool, now we have at least 3 bugtrackers, totally out of sync.
