What has happened to my staked nodes?

When I logged into my wallet today (haven’t done in a while , prob about a year) it indicates I have no staked nodes (had 15). Can someone please tell me what has transpired ?

Thx for your help

Hi! If you were using a 3rd party node hosting service provider, please reach out to their support. There were few of provider left our ecosystem and unstaked the nodes under their control.
