Dunno why but every pad change I've done on my Scenic has left me with spongy brakes.
So I bleed once after pads fitted (before wheels on) and have needed to repeat a day or so later on rear pad changes.

If discs wheren't changed, the new pads will need some miles to bed in.... this can be a couple of hundred miles depending on how much wear and tear were on the discs so take it gently and avoid hard braking until they do bed in.

Rears may also not be adjusting properly giving excess travel

When you fit these, wind back piston fully
Fit new pads
Pump them forward on pedal before operating the handbrake
Operate the handbrake first and you can lose adjustment.

Other thing is did you clean out calipers and make sure new pads were free moving with copperslip or similar on contact edges ??

Last but not least.
If fitting new pads to old discs it helps them to bed in if you go over the discs with medium wet and dry to bust the glaze and leave a slightly abrasive surface.

And to remove any lip that may be holding new pads off the main surface
