I keep going round in circles on korean dating app that is widely used by expats and I'd rather ask than guess. With widely seoul, what decides it is how quickly the inbox fills, not the length of the feature list.

Applied to widely seoul, the honest advice is to video call before travelling anywhere, for what it is worth. Seoul apps is where I would start, since nothing improves until you report problems early instead of blocking quietly.
