Hello everyone, Do the "newer" Cloud Key Plus no longer have a built-in battery? I bought one and it switches off immediately in the event of a power failure. The test date 09/20/22 is stated on the box. I found the following: https://community.ui.com/questions/Cloud-Key-Gen-2-Plus-Battery-Issue/9ee06ca6-2e91-41e6-a1d9-68be859f54dd#answer/2d91ccfb-ce9a-4888-a887-9384cd163c5d Can anyone confirm this? Thanks and greetings
