AFter reading the thread here on MCP and also intervals.icu API, I’ve been poking around on my own analysis and ran into a possible issue. I wanted to see if anyone else has this:
Using the public API with password grant (xert_public). /oauth/user and /oauth/training_info return my data correctly (signature, weight, status). But /oauth/activity?from=&to= returns exactly one activity for any date range I try — including from=1&to=2000000000 — and it isn’t mine: “Tough Mixed Rouleur Ride”, 2026-10-11, Garmin Edge 1040, 66 kg, group_sharing: "Squad", image paths under /user/6/. None of my ~130 activities since June 2026 appear. I’m not in a Squad and have no coach. Looks like the activity list is scoped wrong on the server side.
