Hello,
when using the Transaction ID-field in the Adobe Analytics tool-section, the transaction ID is not set in the s.tl()-call of the corresponding rule. I have to include "transactionID" to the s.linkTrackVars variable manually in custom code section. This is very confusing and not documented.
Therefore I suggest to include the transactionID in the s.linkTrackVars variable by default, if it is set in the Transaction ID-field.
Best regards,
Frank
