When adding new waypoints or changing existing waypoints, the app keeps showing the old ones untill refresh. So far nothing special.
Only, when deleting waypoints via the website, the refresh in the app will not work. When adding/changing waypoints, those will be updated upon refresh, but the deleted waypoints keep showing up in the app.
The only way to remove them (by the user of the app, not by me as cache owner) is to delete the app data trough the android menus. Only removing cached data will not even work...
I have reproduced the situation, but as a multi-cache owner I find this very unconvenient. I have serveral logs pointing out the inconsistency also. So it is confusing for the cacher.
