Yours is very old.The latest one is r157.Update it and then retry
Thank you so much, I found out that when I install construct 3 as app, it is not...update even I check for update in the setting.
However, after reinstall with latest, problem still.
I'm trying your sample project but after export to ios, the same error happens. Look like something wrong with "unsupported URL" that result "configuration failed" (note that I tried to chang my policy url with and without http:// )
