We noticed an issue with our Page Rule group condition. The AND group condition was behaving like an OR in some situations, while the Page Rule debugger was working properly. We have shipped an update with a fix which is rolling out now.
In case your page rule is now behaving differently on your website (and you have multiple groups), please check your page-rule settings, correct them and publish your changes.
⚠️ This was only an issue for a Page Rule that had multiple rule-groups and were set to the AND condition. All groups in the or won't be affected for this update.
Situation explanation
The AND/OR selector inside groups were always working properly. Inside the editor AND on live sites (which is shown as a group with a green border).
When you have multiple groups for a page-rule, the AND/OR was not working properly on the live website, but was in the editor (which is shown in orange).
