The wallpaper I posted wants to be synchronized to a mobile device, but it needs to be signed with a third-party license. After finding the third-party license, I opened the button without signing the agreement, which caused it to be unusable. Please let me know where to sign the third-party agreement for the mobile device.
Note: On the Wallpaper Engine purchase page, it is necessary to agree to a third-party end-user license agreement
"Wallpaper Engine EULA" opens the button that does not accept or agree to the agreement.
