KeeShare live synchronize issues

[Tau512]

Client1: Fedora using repo keepassxc
Client2: Win10 using keepassxc msi installer.
Sync method: Owncloud (using owncloud desktop sync application)

Expected Behavior

when configuring KeeShare, 'synchronize' should allow a multi-way sync between all clients with access to the shared file with immediate 'live' updates.

Current Behavior

KeeShare enabled groups only update either at initial configuration of keeshare, or unlocking of kdbx.

Possible Solution

sugestion: KeeShare does not appear to honour the 'automatically reload the database when modified externally' setting. KeeShare should honour this setting to allow immediate visibility across all synced devices.

Steps to Reproduce

1. Client1: existing database, in settings>keeshare enable import&export, & configure 'Own Certificate' section.
2. client1: create group & enable keeshare as Synchronize, path to Owncloud location, configure password. Create a password entry to test.
3. client1: ensure DB is saved & check file.kdbx.share has been created & synced.
4. client2: create new DB, setting>keeshare enable import&export & configure 'Own Certificate' section (different name & cert details than client1)
5. client2: create group & enable keeshare as Synchronize, path to Owncloud location, configure password. Note that when selecting existing file.kdbx.share, it prompts to overwrite existing file.
6. client2: see that the entry created in step2 is visable.
7. client1: create second entry & save
8. client2: wait for owncloud to sync and see that new entry is not visible.
9. client2: close KPXC/lock DB and re-open. see that the password list is correct between the two clients.

side notes:

1. 'automatically reload the database when modified externally' is ticked on both clients.
2. KeeShare Imported Certificates shows the other client on both client1&2 as trusted.

Context

currently testing new feature with the view to use at work for 4man team.
