Hi Katherine,
SameSite Cookie
I am wondering if this issue is connected with Chrome’s enforcement of the SAMESITE cookie requiring the values of “None” and “Secure” to be set otherwise third party tracking cookies are blocked from passing their values back to Infusionsoft.
Blocked Tracking Code
So Infusionsoft isn’t seeing or recording the tracking cookie results. Maybe this is preventing the JavaScript web forms from being displayed, if Infusionsoft isn’t seeing their tracking code feedback? I don’t use Infusionsoft’s JS based web forms so haven’t tested this theory but it seems very likely to be connected.
Rolling Enforcement
Google is rolling out enforcement over time, see the latest July 28, 2020 update. Enforcement is only being applied to an ever increasing sub-set of Chrome users, which might explain the fact of the JS web forms working then not working, depending on whether your Chrome browser is in the enforcement sub-set.

Prior Thread Discussion
I raised the issue in this community forum thread:
Non-Compliance by Infusionsoft
Using developer tools to look at my own website I see Infusionsoft’s cookies have these values set, none of them include the new SAMESITE values of (None, Secure).
InfusionsoftTrackingCookie - (Secure)
GCLB - (HttpOnly)
JSESSIONID - (HttpOnly, Secure)
Anyway just my speculation really, without more in-depth testing, but all factors might clearly explain the sometimes works, then sometimes doesn’t work effects people on this thread state they are seeing.
