Yes, we are using postMessaging to pass data between them. Our site is composed of multiple single page webapps, but they are all on the same top level domain. Some of the webapps have Launch in an iframe, and some don't. When you go from a webapp not in an iframe to one that is, the last clicked value in the non iframed webapp persists to every server call in the iframed webapp.
I've looked into some documentation and the only cookie I've found mentioned is s_sq. If we manually set this cookie outside of the iframe, would Launch be able to use it properly?
Right now normal behaviour seems to be that the s_sq cookie gets basically cleared after a server call, however when the server call is made inside an iframe, the cookie is not cleared. We could try and clear it manually after each iframed server call, and have the webapp set the cookie manually.
I'm pretty new to activity map, so sorry if this has been a noob question lol
