Hey Dory - Yes, it definitely did help. Pre-forms 2.0 we had campaigns that were using API calls that triggered our trials, but they all start with a data value change and weren't processing the lead fast enough, resulting in delays between the user signing up for and receiving their trial information. Our former Marketo Admin contacted support about it and their suggestion was to change around out flow step to improve
campaign processing.
Additionally, turning off any "inefficient" campaigns helps this quite a bit as well in regards to campaign processing.
