Some more Edge Panels examples
Existing (currently installed) Edge Panels should continue to work just fine on devices running One UI 7, but users will no longer be able to download them if they happen to uninstall them. This goes for both free and paid Edge Panels.
Apparently, Samsung is starting to give some people the heads-up so that everyone is prepared for the change, as reported by X user CID (via SamMobile). The company hasn’t given any reason why they are limiting access to Edge Panels, but it’s quite possible that they just weren’t popular enough with Samsung’s user base, or that the feature has become redundant.
As for users who have to stay on One UI 6, for whatever reason, Samsung is saying that their access to the Edge Panels store page will continue (at least for the time being).
