With myPWS you can export your data cache to iCloud Drive on one of your devices and import the exported file to myPWS on (one of) your other device(s).
Then do this on one for your other devices:
Attention: importing a cache file overwrites the existing data cache on the target device!
Please note that all your devices must use the same iCloud account and thatiCloud drive must be enabled for myPWS. Instructions can be found here.
