Vias don't connect. Convert them all to free pads. Give them all the same
designator (98, 99, etc.), then you can make unique rules for connect style
(solid, etc.).
TQFP - probably clearance rules. The space between the pins, along with the
track width of the polygon lines and/or the clearance rule won't allow a
connect. Adjust the settings, or draw a trace to a (similar) free pad.

Subject: [PEDA] Weird - via won't join GND polygons
Well, this is weird. I have GND polygons on top and bottom layers of a
2-layer board. Very standard. To fulfill connectivity, I drop vias
(35/28mil) around to join the two planes, and as expected, they pick up GND
as their net. Then dbl-click the planes, select each one, and have it
rebuild.
The vias are isolated.
They're definitely in the GND net. So are the planes. The Polygon Connect
Style rule is set to Relief-Connect, using 90deg 30mil tracks.
I know this is something simple, but it's eluding me ...
Hrm - just noticed, the GND pins on the TQFP chips aren't joining the GND
planes either. The GND side of the decoupling 0805 caps are joining just
find though. Ah, got that one figured out - the relief traces are too big -
changed it from 30mil to 20mil, and now they join.
But the via are still isolated.
