Purchase events not recorded in Enhanced Ecommerce for Android app

Question

I've been working with an agency specialized in mobile development to install Enhanced Ecommerce with GTM on a mobile app. Screen view tracking and custom events are working fine, but we're struggling to get all data showing in Ecom reports.See current Product List Performance Report (yes, not all data makes sense yet)

It seems the product checkout is tracked properly, but purchase events are flawed. FYI, both checkout + purchase data are sent with a custom event, on click of a button. Event reports show that the events themselves are collected OK.

Here are some of the data pushes (Android):

Clicks

{ecommerce=
 {click=
  {products=
   [{quantity=1, name= Beer, price=12.12, category=Beverages/Beer/Beer-Import, isNewPrice=No, brand=Miller Chill, id=00000_000000003410034805}], 
    actionField={list=Category Browsing}}}}

Add to cart

{ecommerce=
 {add=
  {products=
   [{quantity=1, name= Beer, price=12.12, category=Beverages/Beer/Beer-Import, isNewPrice=No, brand=Miller Chill, id=00000_000000003410034805}]}, 
   currencyCode=CAD}}

Checkout

{ecommerce=
 {checkout=
  {products=
   [{quantity=3, name= Beer, price=12.79, isNewPrice=No, brand=Miller Chill, id=00000_000000003410034805}, 
    {quantity=1, name=Lime A Rita Beer, price=16.99, isNewPrice=No, brand=Bud Light, id=00000_000000001820019987}, 
    {quantity=1, name=Lime-A-Rita Beer, price=1.9899999999999998, isNewPrice=No, brand=Bud Light, id=00000_000000001820000960}, 
    {quantity=1, name=Lime Beer, price=21.99, isNewPrice=No, brand=Bud Light, id=00000_000000001820014990}, 
    {quantity=1, name=Premium 4.8% Can Beer, price=8.99, isNewPrice=No, brand=Bitburger, id=00000_000000002050700011}], 
     actionField={step=1}}}}

Purchase - fired on the same page as checkout (1 page checkout), but with a different event

{ecommerce=
 {purchase=
  {products=
   [{quantity=3, name= Beer, price=12.12, category=Temp, isNewPrice=No, brand=Miller Chill, id=00000_000000003410034805}, 
    {quantity=1, name=Lime A Rita Beer, price=12.12, category=Temp, isNewPrice=No, brand=Bud Light, id=00000_000000001820019987}, 
    {quantity=1, name=Lime-A-Rita Beer, price=12.12, category=Temp, isNewPrice=No, brand=Bud Light, id=00000_000000001820000960}, 
    {quantity=1, name=Lime Beer, price=12.12, category=Temp, isNewPrice=No, brand=Bud Light, id=00000_000000001820014990}, 
    {quantity=1, name=Premium 4.8% Can Beer, price=12.12, category=Temp, isNewPrice=No, brand=Bitburger, id=00000_000000002050700011}], 
     actionField={revenue=101.56, tax=0, id=f0deeb4a-7552-493a-a113-ea9ea356b6e8, affiliation=Mobile, shipping=0}}}}

Do you see anything that would prevent Google from recording a transaction? All tags are also set with "Enable Enhanced Ecomm" and "Use data layer = true".

Thank you so much,

There is an issue with the Google Analytics data package, which is limited by 8192 bytes. Once crossed the transaction is dropped silently.

Our solution was to send minimal data (product SKUs, quantities and prices) while importing the metadata periodically into the Google Analytics dashboard via the API or manually.

Shout out to Guy Korland for pointing it out on Twitter.
