Current behavior

• groupBy not working with ion-infinite-scroll on ionic4 when I load more data form server. For example, the array length is 10, I load 2 new data, but the new data not group . It's group old 10 data without 2 new data

Expected behavior

• When I load more date form server the new array should be group auto

@danrevah Thank you, but can you provide a complete example with source code ?

Just try to replace the pipe with the impure version.
Let me know if it helped.

If not, please upload a small code example that represents the problem.
