iOS Autofill not syncing with app - Safari Data History?

So the title suggests the same as other people have posted in the past.

It seems like the actual Bitwarden App is updating itself with the vault no issues, but once you try and autofill within an app, it’s still using the old data.

Someone on Github pointed out clearing the Safari History, and Data made it work for them, this has worked for me too.

At the risk of sounding like a fool, if clearing the Safari History and Data is solving this autofill issue, does this not mean that Safari in actual fact has this password cached in its data, instead of pulling from Bitwarden?

If this is the case, doesn’t this mean that the password data is actually stored and potentially exposed within Safari and no Bitwarden?

I notice you need to login to Bitwarden to get it to autofill, but it’s not pulling from the vault, but rather what seems like a Safari cache?

I could be completely wrong and was wondering if anyone had a better idea?
