In the Strava mobile app, when an activity description contains a link (URL) and is longer than the space shown in the activity view, the description is truncated — and the “...see more” (or “show more”) option no longer appears. As a result, the full text cannot be viewed in the app.
Previously, it was possible to expand long descriptions using the “see more” link. This behavior has changed recently (oct 2nd it still worked). The issue only affects the mobile app; on the web version, long descriptions (including those with links) can still be fully expanded.
So you messed up something with links in description in the last 4-5 weeks or did this on purpose?
