I deleted a activity (was synced from Strava)
After that, more than this activity (in sum ca. 159) were marked as deleted.
After i marked all deleted activities in the list and clicked on undelete all these activities are completly deleted and I can’t see them anymore.
is there a way to resynchronize with Strava to get these Activities back to intervals.icu?
Undelete can take a while.
Wait a bit before doing other manipulations and see if they come back.
OK, thanks. i try to be patient…
Hopefully i haven’t destroid more than this in the last 5mins. 
perhaps i have to delete some activities again…
ok, this is a bit scary now.
i done my commute ride home just now.
It is synced and i see it for a few second in my Kalendar. then it disappears and i find it at the deleted activities…
But now i have the solution… my fault, because the checkbox include commutes was unchecked… 
Seems i have some work to to… because the deleted ones seeems to be the duplicates from garmin and strava
Intervals.icu will delete Strava activities if there is a matching activity from Garmin (or Suunto etc.).
Is there a way to prevent this? There’s parts I like about the Suunto recording and parts I like from my Wahoo.
Particularly power data from my my wahoo.
I’m not keen on un-linking Suunto from Strava (for non bike activities), but I don’t see how not to. I’ll try and find out if there’s a way to only manually push from Suunto to Strava - this would solve the problem.
Edit:
My workaround is:
It’s a bit of mucking around, but it keeps my swimming and walking on Strava
Edit #2:
This didn’t fix the problem, as I hadn’t unchecked the download activities button next to Suunto.
I’ll try again 
Edit #3
. Un-Checking the box retains the Wahoo data
