Hi,
I have the same issue on my computers with synced tabs.
Every time I restart my browsers it generates a new entry in opera://activity.
Tested on fresh new install on 2 VMs and a new account. Browsers are up to date. Once tab sync is enabled, it starts duplicating devices. But only 2 devices are listed on sync.opera.com.
Resetting passphrase does not fix it, duplication continues from zero.

I've the same issue. Looks like device ID in synced tabs changes every times you restart your browser, generating a new device entry in opera://activity.

I ended up disabling tab sync until they fixed it.

Same issue here. SCP error.
Flow trying to load script file with a SCP directive restriction on https://flow-dev.operacdn.com.

Sync error sometimes occurs, device is disconnected from Flow.
New duplicate devices appear in Tabs (opera://activity/) each time browser is restarted. Resetting passphrase only cleans devices list, but duplication continues.

@max1c Since some major releases, sync is not the strong point for Opera.
Lot of issues with duplicated devices in Tabs (opera://activity/) and random logout from Flow and account.

Server issue with the CSP policy, it's the dev domain name (flow-dev.operacdn.com) that is specified instead of the production one (flow.operacdn.com).
We have to wait for the Opera team to fix it.
