Regardless of the above outstanding question, the voting period has elapsed (including any possible extension to the voting period as per Process for aliases, auto-connections and tracks) and the votes stand at +2 for auto-connection so this request will be granted.
@khiemdoan note your current personal-files plug lists both read and write for ~/.ngrok2 but write is a superset of read so there is no need for listing read as well. Can you please remove read from this and upload a new version of the snap, then I can add the override to the store to grant this.
