The latest episode of Relaxation Therapy Tips (Episode 54: It's Black and White) was published on Podiant on March 29th. However there seems to have been some issue with it passing on to various places to allow you to listen to it, such as iTunes and Stitcher. If you're having problems, remember that you can always find the latest episode on Patreon for free once it has been published to the world. You can also find the episodes and listen to them on Podiant itself.
I have re-published the episode today - with the abbreviated title of 'Black and White' - and it seems to be getting picked up now. Please let me know if you're having any problems getting hold of episodes and I'll do my best to sort it out for you.
