While investigating the issue you and other Sooloos users are experiencing with accessing Tidal on your systems, we have been made aware that Tidal are planning to decommission the current login process used by Sooloos and replace it with a new method which is incompatible with the Sooloos platform. This will affect all Sooloos systems, not just those experiencing problems at present. In light of the development freeze of Sooloos, which we announced in March 2019, this means Tidal integration will no longer be supported for Sooloos users.

Our recommendation for customers who wish to continue using Tidal is that they should migrate to the Roon streaming service. All Sooloos endpoints are compatible with Roon and the positive feedback we receive from customers who have already made such a move indicates that Roon is a natural successor to Sooloos.

Your Meridian dealer is aware of the situation, so please contact them to discuss the options for your particular requirements.

Will this mean I can use 861v8 as endpoint with Roon?
