[Discussion] TNAS mobile no longer works with my F5-221

Apparently my F5-221 is now defunct for any connection to TNAS mobile because the operating system is now obsolete!
Is this going to also happen with my other TOS 6 devices that can't be updated to TOS 7 in the near future?

The latest version of the TNAS mobile app is compatible with TOS6–TOS7.
If your F5-221 is running TOS5, please use the version specifically designed for TOS5:
Android version:
https://download3.terra-master.com/Apps ... .4.045.apk
iOS:
https://testflight.apple.com/join/YSghe3QC
(iOS users must download via TestFlight. After installing via the public beta link, the version number displayed in TestFlight may be 3.5.078, but the version number within the app will be 3.4.xxx.)
Reinstalling the TNAS mobile app will cause you to lose your OTP authentication. Please first remove the OTP authentication from TOS. After completing the TNAS mobile app authentication, re-add the OTP authentication.
