I'll settle for when shared iCloud albums support a decent size and resolution. iCloud Photos is frustratingly bad, but I don't want to buy into other cloud ecosystem, like Google's. Does anybody know if it's possible to replicate the integration with Photos on both iOS and macOS, so I could write my own sync thing?
Not aware of those issues, what exactly are the limitations?
