I’m working in some ads creatives and I have to validate them using the tool here. The only problem it detects is that I’m using an external file, referring to the font. I guess Typekit will be capable of handling this, it is made for it but I’d like to ask this community for past experiences, did this cause a problem? Did it turn ok for you?
The detailed problem is:
Relative asset check
The creative calls a file hosted by a third party, which could be an issue if the third party cannot handle the high server load that display campaigns typically generate. To learn more about the referenced file and to confirm that the third-party server will be able to handle the load, contact the creative developer.
