1.8.243 (released today) fixes it with a new local_app disk rooted at storage/app again: https://github.com/freescout-help-desk/freescout/commit/1a9c5b8d

Since app updates are delivered in sequence, publishing both would take every instance through 1.8.242 for a while. During that window old attachments fail to open, and new ones are written to storage/app/public/attachment and have to be moved back by hand after 1.8.243 (mv storage/app/public/attachment/* storage/app/attachment, as suggested by the maintainer). Would it be possible to go straight from 1.8.241 to 1.8.243?

Thanks for packaging!
