You may have gotten into the ‘special’ area by mistake.
If you see this in the upper right corner (notice the S in pink)
Click on profile
Check the box beside ‘Regular’
And then you should be able to see all your routes again on the Routes tab.
Also, the area around the profile will show again.
How did this happen?
You clicked beside ‘Special’ and there are NO routes for your district in that area.
