Crickles – anyone else having issues

Hi there, I have been using crickles (https://crickles.casa/navigator/) to monitor cardiac fitness alongside Strava. And it’s been great. But since April it has stopped providing any info on sustainable levels (my LTHR is now zero apparently). I’ve dropped them a couple of emails but unusually no response.

Anyone else having similar experience?

Working ok for me, sorry.

Working fine here too.

Mine is fine too. I’m surprised you haven’t had a response to emails. On the odd occasion I’ve had a problem Ian has been back to me pretty quickly.

Must be a prob w my feed then. Ian has always been pretty responsive,  I’ll give him another go.

Cheers
