Can you help me?

This is an issue with the sync server and we’ll need to get someone from the support team to investigate it. Please open a ticket at https://support.mongodb.com/ and someone should help out.

ok

Meanwhile, I tried to delete the realm when I get this error, but it is already open!

try
{
	vRealmDb = await Realm.GetInstanceAsync(config);
}
catch (RealmException e)
{
	Realm.DeleteRealm(config);
	vRealmDb = await Realm.GetInstanceAsync(config);                            
}

this is exception:

Cannot delete files of an open Realm: ‘/data/user/0/com.gigios74.Talk/files/mongodb-realm/talk-dajgo/614512cb063503f6b46fc8c7/s_cs.realm’ is still in use.

Why Realm is in use?

It’s because Sync is still using it - it will eventually release the Realm file, but it’s not immediate.

5

Can I release programmatically?

6

No, this is handled internally. You can retry the deletion while sleeping in-between.

If I have a DOWLOAD error, I store in AppProperties a precError and I crash app.
At AppRestart, first Delete.

if(precError) Realm.DeleteRealm(config);
vRealmDb = await Realm.GetInstanceAsync(config);

this works
