So, I have a Problem with the actual Version:
After the initial adding of two devices (one with 2-factor-auth, one without) both devices update their location.
I set the interval to 1200 seconds, but when they try to update i get this error:
Device update of “iphone” failed, ICloudError: Unknown error [450]
I had one device activated today with a interval of 600, wich worked, but then i changed the interval to 1200 and now it doesnt update.
i will wait if it successfully updates once in the next hours and if not set it back to 600 and report back
