Dashed line in Trends not showing

Issue:

The Trends 'Target’ view no longer has a straight dashed line (from the top left corner of the rectangle to the bottom right corner)

Dragging my finger over it for the days in the future shows the green target dots where the line should be, but there is no line. Notice also in the very bottom right corner, there is the ‘stub’ of the future graph / the line ?

I thought to myself, am I imagining that it was ever there? But no, the help text for Trends still talks about it.

What I’ve tried: Uninstall app, reinstall, log in, go back into Trends. Problem persists.

Details to reproduce:
Go into Trends tab, select Target view

OS:
Android 16, security updates up to date through 5 December

Device:
Google Pixel 6 Pro

App Version:
7.5.0, latest available on Play Store

Screenshots:

Is it a contrast or screen issue?

Looks like it starts bottom right but stops.

Fine iOS.

No, there’s definitely no line. The bottom left half of the rectangle has a pale pink/orange background, and the top right has a pale green background, but between them there is no line, dashed or otherwise

As an additional attempt to fix, I have put a device restart in between an uninstall and reinstall, but it hasn’t helped.

Mine no longer has it either. iOS.
