I started a google A/B experiment with bla.com/a as the original page my.bla.com/#/?source=a as the variant page.
I can see the redirection is happening when I land on the original page, but on the result table it's showing 0 sessions on the variant page after 3 days the experiment has been running for.
My variant is a subdomain single page app of the original one. If I change the variant page to my.bla.com without the params it works. Anyone could help?
My educates guess is that "my.bla.com/#/?source=a" does not work as variant URL in the report section since Google Analytics tends to ignore everything after the fragment identifier (#). So from the POV of the reporting interface my.bla.com/#/?source=a and my.bla.com are identical URLs.
It should work if your remove the fragment identifier either in the code or via a view filter. Then you have my.bla.com/?source=a as URL, and GA can read query strings just fine.
