Can't remember other Apple ID - Lightroom 'restore purchase'
I have a subscription to Adobe Lightroom mobile through Apple, and I've logged in on a new phone. Its saying I can not restore the purchase as I am logged in with another Apple ID (which I can't remember - and I have tried all 3 of the email addresses I've ever had).
How do I find the old Apple ID that has the purchase to the subscription?
I contacted Adobe twice and both times they said it was a problem with Apple as Apple are the ones who provide only the mobile subscription for th 4.99£ a month.
