User ID tracking doesn't match Tracking source, Please help
We just start to use user id into our register page. The idea is after a visitor finish register, we will send user id back to GA. However, we found in the user explorer report. The user Acquisition Channel are all in "direct" Channel. It doesn't match the actual Acquisition Channels.
We check the original report (default view) and find the same user was from paid channel. We don't know why GA doesn't synchronize the user records
Please see the following screenshots:
The following screenshot is from default view's user explorer, it shows the user is from paid channel
the is the cookies
The same user in user id report, GA got the user id we send, but the user is from direct channel instead of paid channel, and it show less user view history
How to fix it?
