is comaps data updated only when the app updates? (lemmy.world)

I added some data on local shops in OrganicMaps and StreetComplete. My changes are visible in OSM online but my (just downloaded) maps in CoMaps don't show them. I found this issue for OrganicMaps that says maps data is updated only when the whole app is updated and I assume CoMaps works the same.

Are there any structural reasons why this is the case? Or is there a possibility/plans to have maps data refresh more frequently?

Short-lived / Temporary data, like road-work, is not mapped in OSM, so that's not a concern.

    I tried researching this a bit and you are right that it's not a Comaps-specific issue but more with the general OSM ecosystem.

    It seems to be a chicken-and-egg situation in the sense that there are ways to tag temporary closures but they are not recommended for short-lived data because many apps use data offline and have long update cycles.

    I'm referring to this bit in the page on key:construction

    As OSM data is often used offline (and therefore may be several months old), only tag construction sites (particularly roads and railroads) if they are planned to be closed for at least six to nine months.

    There is some work being done at Google Summer of Code 2025 to add road closures and more real-time events that might impact navigation. I'm looking forward to see if it pans out.

    I don't think that GSOC project has anything to do with OSM other than that they reference downstream OSM data consumers as potential users and wrote a blogpost on their OSM Diary about it.

    It also doesn't matter, because there simply aren't enough people actively contributing to OSM to keep temporary short-term road closures up to date, even if a database for such data existed.
