i've lost all my presets in adobe lightroom

Hey @helpful_video5E5F, 

As @Rob_Cullen requested, please share your exact details. This will help us narrow down what’s going on and more effectively support you. Based on your tag, it looks like you're on a PC and referring to the Lightroom (cloud-based) version. I can assume you're trying to sync presets between a mobile device and your desktop app? If so, check out this article: https://adobe.ly/40CR6hg

However, if that’s not the case and you're using Lightroom Classic—the desktop version that’s not cloud-based—please take a look at this article about missing presets: https://adobe.ly/4f8O8a1

We really want to help, so the more details you can share, the better! Thanks so much.
