I recently got a new phone and when I installed lightroom and logged into my account, all of my inages and user presets were gone. The same problems have been occuring across a number of aps, but for the number of hours a put into those presets..I'm unwilling to let then go without putting the same effort into trying to get them back. Please help
Are you using the free version of Lightroom mobile? If yes, the presets are stored locally on the mobile device & re-installing them may have removed the data related to the app. You can try restarting the mobile device to check if that helps.
