Did you actually hit the save button when it came up with the Notes box after you had ended the ride?
Have you actually tried to refresh your data from the calendar page?
If you look at the horse’s page, do the rides show there?
I find the app always defaults to the “no” messages as it is loading any give page. So “no network connection”, “ride has not been analyzed yet”, etc. I’ve also had rides show up on the wrong day several times this year. Usually the next day (ex. I rode Sunday Nov 19, and the Equestic calendar has it on Nov 20).
Which brings another question - did you check that the app has permission to access your mobile data?
I did lose a couple of rides I particularly wanted to see once. Uninstalled the app, and immediately reinstalled it, and the basic information was there. I’d lost all the metrics that could bee analyzed for symmetry, impulsion, etc.
Early on I lost ride one of two done on the same day, with no data connection. I don’t remember exactly what I did to stop it happening.
