Hi

The behaviour your seeing is correct, old legacy workflows will open in legacy designer. New workflows will give you the choice to use new or legacy designers.

All workflows will need to be redeisgned in the new designer.

Legacy designer will be supported until the end of regular support cycles for K2 Five (5.0) - 31 December 2020 (Extended Support 2022)

Im sure firefox support is in the pipeline but you can also log that to ideas.k2.com this way you can get updates on the feature.

Using private browser sessions is not allowed with HTML designer. Not sure what use case there is to use provate when designing but if there is any feel free to log it to ideas.k2.com.

So are we supposed to recreate the entire workflow manually in the new designer and then redeploy it?  Is there a way to convert an existing legacy workflow to the new format?

At the moment there is no way to convert legacy silverlight worklfows to HTML workflows. You can once again log this to Ideas.k2.com for visibility.

Thanks Vernon.  The use case for private/incognito sessions is the increasing use of multiple O365 subscriptions by users.  This can be a combination of their employer, other projects they collaborate on, and/or their personal subscriptions.   Unless you fully clear the cache each time the standard session cannot be reused between O365 SharePoint sites without 'invalid sign-on' type messages.  So, we have gotten around that be using (and telling others) to use private sessions.

Yeah credential switching is tough in cases like this. I think your best option is to log that on the Ideas.k2.com site. Our PM team monitors that and if there is an update on the item you'll receive a mail notifying you.
