When sharing a device using the Tuya App version before 3.34.0, if another phone has installed a version after 3.34.0, clicking the link will not directly open the app, but will redirect to the download page to guide the download of the app. In this case, the two phones should have the same version of the app installed. You can delete the lower version of the app and download it again. This is because Tuya has distinguished between the international and domestic markets since version 3.34.0, and has removed the original app from the domestic market. A new AppID app has been re-listed in the domestic market, so links generated by the app before version 3.34.0 cannot open the app after version 3.34.0.
