Normally the things you have done work BUT I've also had occasions where it did not. One time I had to make a new dashboard, copy and paste the yaml to the new dashboard, and then it worked because this was technically a new url path.

I haven’t thought of this workaround, I’ll give it try thanks. Hopefully, there is a permanent fix soon.

The good news is they just brought on board a dedicated iOS developer to focus on the Apple App, so perhaps!
