App links (mailpring://…) stopped working for me when switching from 1.8.1 to 1.9.1 (I skipped 1.9).
I am on Gnome Manjaro, update as of 2021-04-21. Clicking on an app link brings forth Mailpring, but then the linked thread is not displayed. I am using the AUR Mailpring version, with a custom modification to the build file to ensure that release 1.9.1 is used.
- Copy a mailbox permalink
- Paste it on another app (e.g. href in a web page)
- Click on the link
Focus should switch to the Mailspring app and the linked thread should be displayed.
Not strictly necessary in this case.
- OS: Gnome Manjaro, rolling relaese, last update 2021-04-21
- Installation methods: AUR version AUR (en) - mailspring with the fix suggested in the comment to ensure that v 1.9.1 is employed
- Mailspring Version: 1.9.1-30ef802f
No extra context seems to be relevant
