Platform.sh mounts created relative to .lando.yml, not .platform.app.yml

[dwkitchen]

I have a multi-app setup with .platform.app.yml files in the folders for the app

.git/
.platform/
drupal/
  .platform.app.yaml
  ...
angular/
  .platform.app.yaml

ref: https://docs.platform.sh/configuration/app/multi-app.html#discrete-code-bases

drupal/.platform.app.yaml defines a set of mounts:

mounts:
    '/web/sites/default/files':
        source: local
        source_path: 'files'
    '/tmp':
        source: local
        source_path: 'tmp'
    '/private':
        source: local
        source_path: 'private'
    '/.drush':
        source: local
        source_path: 'drush'
    '/drush-backups':
        source: local
        source_path: 'drush-backups'
    '/.console':
        source: local
        source_path: 'console'

When running lando start the folders are created relative to the .lando.yml file not the .platform.app.yml ie:

/web/sites/default/files, but should be /drupal/web/sites/default/files

I tried adding the following to .platform.app.yml as https://docs.platform.sh/configuration/app/multi-app.html#explicit-sourceroot but this didn't resolve the problem.

source:
  root: drupal

Tell us about your setup

v3.1.4 on Mac OS 11.5

Tell us about your .lando.yml

I'm noticing the exact same issue. It doesn't seem to matter whether I use one applications.yaml file or multiple .platform.app.yaml files with or without source.root specified.
