Hey grannyplayz,
This was actually changed all the way back in Season 18, with Revenant's rework. You can check the blog here for the full details, but I've put the relevant portion below as well. Essentially, you'll be getting a badge rather than the dive trail.
RANKED REWARD REWORK
In previous seasons, players achieving Diamond+ ranks would get access to an exclusive season-long Dive Trail.
We’ve been observing an unintended effect where the presence of a Ranked Dive Trail during the drop would unduly influence where players wanted to land—either strongly avoiding or actively pursuing players with the trail.
A reward for being a top player shouldn’t give away valuable information at a critical part of the match, so we’ve made a change to swap the Dive Trail reward with an Epic Banner Frame as the Diamond+ Ranked reward.
- The Epic Banner Frame lets players flex their hard-earned status at the start of a match and more importantly, every time they take down other players.
- Badges, Holosprays and Weapon Cosmetics will continue to be rewarded in Ranked as in previous seasons.
