Yeah some people it doesn't work as well for. I've had nothing but good results with the new version luckily.
Have you tried it since changing to yakihonne? I see your relays are much more minimal now, that may actually help. I notice a lot of people have double digit in & outbox relays, which will actually make it worse rather than better. 2 or 3 is the sweet spot.
Also clicking the "default" button for any that have it in the settings may help too, search & index that's especially make a big difference when they are set correctly.
