Hi Tatiana, I took a look at all of the screenshots you sent. There are definitely some things that look like they need to be double-checked or perhaps changed.
1. For example, in screenshot #1 I see that the deprecated SDK Endpoints are being used, and screenshot #6 I see that the newer SDK Connections are being used.
2. In screenshot #4 I see the warning about needing to add a Metric in order to view results (which is correct -- a Metric does need to be added). You can see this is true by cross-referencing screenshot #3, where the Activation Metric is set to "None".
3. In Screenshot #2 it says the SDK was loaded successfully, but it's not clear what experiment(s) or environment(s) that applies to.
Can you send a screenshot of the Overview tab of the Tatiana Test experiment?
