Bisync would sync all files even though check shows only 2 changes

welcome to the forum,

roundsync has not been updated since Sep 10, 2024 and it is not a fork of rclone.

fwiw, i run rclone natively on android.
i have a handy, dandy howto guide

maybe try the following

  1. re-run the commands with -vv for debug output
  2. pick one single file to focus on.
  3. on the source file and on the dest file,
    run rclone lsf --format=psth
  4. post the output
