The Netherlands and Sweden each survived scares as they secured first wins in Group C having drawn their Women's Euro 2022 opener.
The two pool favourites would have considered their meeting last week the toughest test of the first stage of the tournament, but Portugal and Switzerland were no pushovers on Wednesday.
Those two had played out their own entertaining draw, and Portugal repeated the two-goal comeback that rescued that point.
The Netherlands were coasting after a pair of headed goals through Damaris Egurrola and Stefanie van der Gragt, but the VAR spotted a foul on Diana Silva late in the first half that allowed Carole Costa to pull a goal back.
And Silva's header from Costa's cross had Portugal level, before the Oranje were again frustrated by a video review when Jill Roord's effort was struck off following a four-minute delay.
The defending European champions finally got their act together, though, and Danielle van de Donk arrowed into the top-right corner to earn a 3-2 Netherlands win.
It had been a similar story in the early game as Sweden beat Switzerland 2-1.
Sweden were the beneficiaries of a VAR review when Noelle Maritz went down easily and a penalty award was overturned, before Fridolina Rolfo steered the world's second-ranked side in front.
However, a fine Ramona Bachmann finish only 92 seconds later had Switzerland back on terms.
Teenage Sweden substitute Hanna Bennison restored the advantage with a 20-yard drive, yet her side were never in real comfort as they saw two late goals ruled out for offside.
