Problem - The nice preview of tracklogs when sharing is missing from some tracklogs and visible on the rest.
The tracklogs are public, I open them and copy and paste the URL into facebook
Example - Works all ok
Tracklog ; https://www.myrouteapp.com/track/open/593178
result:
Example - Does not display preview
https://www.myrouteapp.com/track/open/593815
result:
For the problem tracklog I have tried renaming. altering public private back to public etc, but still the same result (the link does work and open, just be nice to show the same preview as the working one, (track log title, thumbnail of route, distance, time, avg speed etc)
Hope that makes sense, probably outside the remit of its core use but if someone has time then great, many thanks
The FB page I am sharing them from is

@big-vern so this usually happens when the initial privacy was private and the preview isn’t generated.
Well…it actually is but not with the nice image etc.
FB then remembers this is the preview and when you fix the issue in MRA, FB doesn’t retry this just yet.
Usually after a while it will

Many thanks ! - I deleted the FB post re-added it a few hours later, (same result no preview), so then I emptied the FB trash bin (with the all the old deleted attempts, (its FB page and dint realise it had a trash bin)) and left it overnight
Added same url this morning and it worked perfect with the preview
Once again thanks for your help and responsiveness, keep up the excellent work.
@Corjan-Meijerink
Maybe I spoke to soon, the post (same url https://www.myrouteapp.com/track/open/593815 )
is now getting deleted after a few minutes, just FYI,
@big-vern Happy it worked.
Why facebook is being stupid now, no clue
I know we share a lot of those links without any issues!
@big-vern, probably because of posting the same link multiple times in a short time or something...
