I have several tags/triggers in Google Tag Manager( both script/non script versions - https://www.googletagmanager.com/gtm.js and https://www.googletagmanager.com/ns.html) that clearly show up in the old version of GA (Universal Analytics) under Behavior>Events. These triggers have existed and worked for the past several years.
I migrated to Google Analytics 4 this past week, but none of the old triggers/tags are showing up under GA4. If I switch between GA4 and GA, I can clearly see the triggers firing in GA, but not in GA4. In GA4 I'm looking under Reports>Engagement and Realtime>Event section.
There's obviously several new events built into GA4 that are visible, but none of the custom tags I've been using.
Do these not migrate with GA4? I'm having similar issues migrating conversions that use RegEx.
