Hello, reitti has a different usecase than wanderer. Reitti is designed to follow your whole day around. The idea is to look back a year from now to bring back some memories. With the new map you could also dig into your behaviours like where I am normally at 08:00, or which places I go to lunch at 12. For that, it needs the gps location all day. There are multiple ways to ingest data into reitti. It is documented here: https://www.dedicatedcode.com/projects/reitti/latest/integrations/mobile-apps/
You can also upload GPX Data or other formats. Reitti works best when having a continuous stream of gps data. Think about it as a Google Timeline but private.
Wanderer on the the other hand, seems to be designed as a planning and tracking app for single trips. Correct me if I am wrong.
Hello, it should zoom in into your data or home location. The later can be set in your profile under Settings.
What normally should happen: you open the page and reitti loads the data for the selected day or the data for the last known date to have data. Then it zooms into the whole path until it fits nicely on the screen.
If this is not working for whatever reason please report a bug. Then I can dig into it and try to solve this.
