Update time: August 4, 2023
Although GA4 has been released for 3 years, there are still some bugs in this product. I will introduce some bugs below.
If it’s officially fixed, I’ll mark it
Average Engagement Time Shows 0m 00s
Average engagement time is 0m 00s, such as:
verage engagement time is calculated based on the user_engagement event, so your GA4 has not tracked the user_engagement event, and user_engagement is an automatically collected event, so you can’t make any settings.
Someone encountered this problem in February. The data was normal before, but it became 0 after a certain day, so I guess it is a bug.

Repeated Event in DebugView

This is actually a bug, waiting for the official fix.
Price Is Wrong in DebugView
If you use DebugView to debug e-commerce tracking, you may notice that the price parameter is incorrect, the price you send is 3.15:
The DataLayer.push is right:
dataLayer.push({
event: "add_to_cart",
ecommerce: {
items: [
{
item_list_name: "Product details",
item_list_id: "Product details",
item_name: "CASEME 013 Series PU Leather Mobile Phone Shell with Wallet Stand for iPhone " +
"8/7/SE (2020)/SE (2022) 4.7 inch - Black",
item_id: "101115653A",
price: 3.15,
quantity: 1
}
]
},
gtm.uniqueEventId: 596
})
but it shows 3150000 in DebugView:
Picture Source：measure
Automatically multiplied by 100000, this is a bug in DebugView, but it will not affect the data in the e-commerce report.
Multiple Life Cycle Reports
You may see multiple of the same report in GA4 like Life Cycle：
Reason：When you make adjustments to the report in TOPICS for the first time, and then save it to the current report, a new Life Cycle will be generated.
If you modify the report in different TOPICS and save it, there will be more Life Cycles.
