I have a CSV file with 685 fields. When I try to scroll to the “end” (to the right) to map fields, Connect Design lags to the point where it’s nearly unusable. Are there tricks/settings to resolve this issue?
We are attempting to resolve this issue in the next release, but we are not yet sure if the lag issue will be fully resolved. (internal ref# SHARED-90803).
For now, I can only recommend that you convert the file to a more “vertical” format, like JSON or XML.
