"Arguably, you can't fix things with it" - you can fix certain things, thanks to resurvey quests that were added.
For example resurvey of old opening hours data, recent version (v28.0) added also ability to directly handle shop that is gone and replaced by another (it may not be released for you, especially if you use F-Droid). See https://github.com/streetcomplete/StreetComplete/releases/ta... for details.
Ah yeah you're right, I did install the v28.0 version and forgot about this new feature.
Also a big thanks to you for your work on this app, it makes editing OSM super easy on the go, and gave me something to do on my walks during the lockdowns :)
