The 1.0 update is not available yet for Pie (see the original post, third paragraph “Update 31 May”.
As to upgrading to Q or R, for the time being this can only be done manually, i.e. basically a re-install from scratch. Upgrading OTA (i.e. through the updater) with keeping data and settings and the like is still only in testing, that horizon frankly hasn’t gotten any nearer recently.
So you might want to stay on Pie for the time being.
