Not working for subway any more

This used to be a great app, but it appears to be abandoned and not working

Hasn’t been working in ages

Hasn’t been working the last month or more when I keep trying every other day. No times load for any service route. I keep having to go to Google Maps. Don’t want to pay for premium as I doubt that will fix the issue. Can only assume it has some mismatch with updates on my phone because it used to “break” like this (getting no data) every so often. But now it’s been so long that it’s been useless :(
When it works I totally love it! Shows more real and accurate times for the information I’m actually looking for. 5 stars when it works but idk how else to communicate that it’s not working at all.
