I consider this a moderately serious bug.
When I create a copy of a Workflow to send an Email, changing any of the critical criteria parameters such as Email Subject, Email Body, PreHeader, Attachment Name and EVEN THE ATTACHMENT TEMPLATE, causes changes in the original workflow. AND VICE-VERSA - changing the original causes those changes to be applied into the copy.
I do not know if other copied workflows are also impacted.
It’s as if the two are linked - (i.e. referencing the same in memory object).
I can create a NEW workflow and insert the same details and all is well.
This is a problematic blow to those apps that need to create a series of similar email workflows. Having to create a NEW workflow and then copy/paste the details is excruciatingly painful and time consuming.
Sending to AppSheet support as well.
