a couple of days ago I had some connection issues with my mobile app (iOS) called "TNAS mobile".
I wasn't able to reach my nas F4-210 (TOS 4.2.41-2203011629) outside my LAN.
I quick checked and it seems this app is no longer available into Apple App Store and the newest one does not support TOS 4 (I think that is the newest software supported by my F4-210).
There is something I can do to fix this uncomfortable situation?
Thank you in advance.
