TICE is a secure app for meeting up, sharing locations and locating friends and family in real-time. TICE allows live location sharing on iOS, Android and the Web. Privacy by Design and modern end-to-end-encryption protect the sensitive location data from others.
When updating other members' locations all markers are being deleted and new markers seem to be added after that. This doesn't look nice.
Additionally when disabling location sharing all current markers get removed.
