We have also been impacted hugely by this change - without any forewarning or explanation of the issue. We moved our CMS to HubSpot from Wordpress in order to improve teh integration of our systems. However, we need to be able to send resumes uplaoded to a CV parser for our recruitment application tracking system. We had a workaround via a partner but this has been switched off.
This has a dramatic impact on our business and questions the viability of moving to HubSpot
