I’ve been reading that its possible to write to a client tag in the mobile module based on the url but I can’t get it to work. I am able to extract the parameters just fine through the webDev module but I have an instance where I’d like to write directly to a tag.

Is the format below incorrect for auto writing to a tag? Thanks!

I couldn’t actually find anything in the change logs, though.

Ahh, maybe I misunderstood what you were trying to do. This would work only for startup of a given project in a new client, not for a running client, and I would expect you to have to pre-create the client tag as a string tag in the project to receive the value.
