Google Tag Manager not firing

I had the GTM plugin working for a long time. I then setup Sentry a few weeks ago. Yesterday I noticed that I wasn’t getting any data in Google Analytics and the last data was the day I installed Sentry. A quick search shows there can be some conflict between the two.

So I removed Sentry from my app and GTM still wouldn’t send data. I then removed the GTM plugin and reinstalled to no affect. I then removed the plugin and added the GTM code snippets to the header and body custom code.

In dev console I can see GTM get initialized, but the page view event on app load never makes it to GA. When I navigate to other pages, I don’t see a GTM entry in the network log of dev console. Also don’t see any errors.

I also tried clearing the cache in Cloudflare.

Anyone have similar issues?
