anyway yeah DELETE YOUR FUCKING ADVERTISING IDS

Android:

Settings ➡️ Google ➡️ all services ➡️ Ads ➡️ Delete advertising ID

(may differ slightly depending on android version and manufacturer firmware. you can't just search settings for "advertising ID" of course 🔪)

iOS:

Settings ➡️ privacy ➡️ tracking ➡️ toggle "allow apps to request to track" to OFF

and ALSO settings ➡️ privacy ➡️ Apple advertising ➡️ toggle "personalized ads" to OFF
