I often switch between devices. No need to log out, but I don't ever have the app running on more than one device at the same time. Even that is probably ok if one of them is static, some people do it during team competitions to keep track of their score.

Apart from remembering to transfer the save each time, I'd suggest paying careful attention to daily rewards as it's easy to lose one. If you open the app and claim the reward, but need to restore progress from the other device, you should then force close the app and relaunch to reclaim the reward, it won't automatically reappear after cloud restoring.
