Did you review places via Google Maps in the past? @mangroveReviews@mas.to now offers a way to import your past reviews, which means they will also appear in CoMaps in future maps!
Eh deleted all my reviews after google accepted a claim that my 3* review of one shitty ass shop in Germany was defamation, ignored my response and removed it. Hell, I'd argue it was net positive review (otherwise wouldn't be a 3* IMO), but the abuse of the system in Germany is wild and clearly Google doesn't give a fuck just like the rest of their products.
Anyway still waiting for opportunity to "transfer" all my photos from google maps. Ever since they changed what counts as storage use in drive, I've used maps to store useful or nice photos from hikes/parks/nature that I didn't necessarily wanna keep stored on the phone.
Edit: ooh this also does mention the export/import of photos. Guess I gotta try it!
