Mobile device mission syncing

Have recently been through my Litchi hub and cleared out a mass of old missions.

However, when I go to my CrystalSky, although it appears to sync with the hub, there is a whole load of old missions still present!

I’ve deleted the app cache and also logged out and back in on the CrystalSky… still the same.

Any suggestions? Many thanks

In GENERAL settings you could try:
-Sync Local Missions: On/Off
-Check and Sync License
