Preview results may be incomplete due to process timeout

When running a preview of a Pack with two lookup functions pointing to 1 million records files, I get the message:

Preview results may be incomplete due to process timeout

If I disable one of the functions - it does not matter which one - the preview works fine.

Is there a lookup limit the preview can handle? The sample file used contains 57 events.

Thanks.

Select the gear at the top right of your open sample. Increase the timeout settings there.
