Resolved Add to Reading List doesn't work...

[qap]

All started on my iPad few days ago, now the same also on iPhone and iMac: I use a lot Reeder for the RSS, but if I add something to RL, nothing happen... also if I add something from the Mac from Safari, it doesn't sync to other devices. All the devices are running the latest OS version.

Any suggestion?
Thanks!

Solved with "Clearing Safari cache and data" on both iPhone and iPad! Now the Reading List works from every apps!
