Forest Calendar Sync

Was/is anyone using this with Google calendar?

sync.ecal.com/button/v1/schedule/?widgetId=5d05e0efe3440501328b4567&apiKey=40638212e3c82318367a0853e96ee2d95d05e061389be

It kept fixtures up to date with changes, and also told me when tickets for my membership were on sale, but it seems to have stopped sync'ing. Dad and brother report the same.

Just added it again, and it seems to be working now. Though I now have two Google calendar subscriptions to Forest and have to figure out how to remove the one that isn't working.
