Presumably it's an attempt (it's been around for a long time) to try and stop people logging into their accounts on other people's devices/computers and downloading and illegally sharing content. The 90 day association should only happen if you do particularly things on an account : View and remove your associated devices in iTunes
Your iPhone, iPad, iPod touch, Mac, PC, or Android phone automatically associate with your Apple ID and iTunes when you:
- Sign in to Apple Music with your Apple ID.
- Download music to your iPhone, iPad, or iPod touch in the Music app to listen to when you're offline.
- Turn on iCloud Music Library.
- Download past purchases that you made in the iTunes Store, App Store, or iBooks Store.
- Turn on Automatic Downloads for iTunes Store, App Store, or iBooks Store purchases.
- Turn on Family Sharing.
- Subscribe to iTunes Match.
When you try to associate another Apple ID with a device that was already associated, you might see a message that says, "This device is associated with another Apple ID. You cannot associate this device with another Apple ID for [number] days." Depending on when you associated your device with your Apple ID, you might need to wait up to 90 days to associate the device with another Apple ID.
Thank you so much for your information. I am sorry about the delay in replying as I have been in transit. I hadn’t encountered this problem previously, so I assumed it to be a new policy. Although I do understand the issue of stealing content, however since I pay for downloads for both, that isn’t the case. I guess I will need to contact Apple to be able to access my content in this case🤔 Although I realise that this isn’t a problem for most people, for some it is. I am not sure why Apple can’t have a program to address this type of need🙁 But, that is a problem for Apple and I to resolve, so it appears...but thank you for your time and insight on the issue😊

Why a 90 day lock out? I have 2 Apple ID’s because I live and work in 2 countries ( recommendations per Apple representatives ). I now find I have a 90 day lick out when going between stores on items I have purchased, this didn’t start until now?
