iOS Google Tag Manager crashing upon Launch with 'NSParseErrorException', reason: 'Last tag: 116 should be 124'
It turns out, this issue can happen if no actual tags have been created on the server end of Google Tag manager.
Our analytics guy ended up doing the following:1. Creating the needed tags on the server2. Generating a new container file which we update in our code
Then the crash went away and everything worked.
