Engagement
Volume and quality did not move together. Device mix explains part of the Paid Social trough for me: mobile is the majority, and Android WebView is more than a third of users.

What I noticed. February 2026 is 64.6% when present. April is 37.5%. July 2026 time is 42 seconds when paid recedes.
How I am reading it. A session increase that coincides with Paid Social usually looks like a quality decrease to me. Time recovering when paid disappears looks like a healthier mix, though one month is not enough for me to call it a new baseline.
What I would look at next. I would keep engagement beside sessions in every paid review.

|---|---|---|---|
| Mobile is the conversion constraint | 54.4% of users, 39.1% engagement vs desktop 65.2%. | The majority device is getting the weaker session. | I would fix mobile landings before buying more in-app traffic. |
