Using the latest version of the Contour app (v. 22.214.171.1241) worked before upgrading iOS 15.6
Now it loads, displays all the chanells, but will not connect to any channel--just three blinking dots like it's buffering--ifinitely
Deleted and reinstalled app; still the same result on either iPhone or iPad.
You are not alone. See here on someone having the same problem since 15.5.
