I've had limited results after reading the info on the last couple of posts (Thanks!). I can share from my phone to my tab, but not the other way around.
Here's my results from following the advice found above:
Start/run iFly on both Android devices, connected to the same wifi network.
Open a flight plan on my Moto X (first gen)
On the second device (Samsung Galaxy tab S4), I cleared any flight plans from being "active".
On the Moto X (with the plan to be shared) I clicked on the menu item "share with local devices".
On the Samsung Tab I click on accept shared plan. Works as advertised.
However, the plan sharing won't work in reverse. Clear all flight plans from active on both devices. Stop sharing/accepting plans. Restart iFly both devices. Connect to same network as before (which works one way). Create new flight plan on Samsung Tab. Click on share with connected devices. The option to accept the share never appears on the Moto X. (Yes, the Moto X is rooted, but running stock Moto X android, not a variant. Only rooted to block Moto X lollipop upgrade).
As previously posted, bi-directonial would be awesome. Anything I can do to help troubleshoot this issue?
