There appears to be an issue with the 3rd party service, which merges Builder data into PDF format. We have checked the third-party website, and they have confirmed they are experiencing intermittent outages with their service. Tenancy Builder will make three attempts to produce the PDF 5 minutes apart. After that, you could edit the agreement and save and build again because the issue is intermittent. We apologise for the trouble, and we will keep monitoring the situation.
