For the past week or so, clicking on the red dots tells me that there is no information available, and this is on locations where I know that information has been available. I uninstalled/reinstalled - same problem. I sent an issue report to the owners - no response.
The paddling locations map is working for me, both on my Windows 10 tablet and Android 12 phone. Sorry I can’t offer a solution, though I will say that “moribund” is a terrific and way under-used word!
I’m having the same issue. I’ve sent their support team an email but they haven’t responded and it’s been about a week. I really have loved using this app and I don’t know what’s going on.
