Vault sharing/sync with 3rd party app not working on android

(repeating a question first posted at discord, as this Discourse platform here allows a much more structured approach for postings …)

I am using obsidian with a vault which is shared/synced through ownCloud desktop app with other mobile Android devices (android 12) and also with desktop clients (Windows and Linux). The issue would
be the same with other sync apps (nextcloud etc.)

When testing obsidian on android, I noticed that the synced vault is not available for the obsidian app on the same device. I assume the root cause is that obsidian is not yet using the storage access framework. Is this assumption correct and will this be implemented later? Details for development:
