@David-TP Thanks David. After Re-Login, It does not prompt to again register for Home Shield Pro.

However, it you go to Parental Controls  or Real Time Protection Section under Home shield, it does not recognize that i already have the Pro Subscription. 

If you click to subscribe again (Either from Parental control or Real Time Pro Tab) , -> It prompts for the network to which we need to apply the subs. -> On confirmation  gives a success message , with button Enjoy Now -> If you click Enjoy Now, app tries to load the Home Shield Pro screen ( with Loading percentage) and it always crashes at 88%.

I have uninstalled the app, reinstalled it again, reconfigured my Deco but it never seems to be working.

After this, if you go to Profile -> Home shield Pro Tab -> it shows that i have subscription but other modules like Parental Control and Real - Time Protection Section, shows that in order to use these features i need to buy Home Shield Pro.

Just FYI - My App version is 2.11.6 and i am using it on ios 15.4

Below screen shot might be more insight.

  @David-TP Hi David, I have tried doing a power cycling but the issue still exists in app.

It crashes at exactly 88%, and post that both Parental control and Real Time Protection Tab is unable to recongise the purchased subscription.

  @David-TP Hi David, FYI - Two days back, I have got a updated firmware for my other issue ( Timezone one), but looks it has only resolved the Date , time is still running behind by couple of hours. But looks after that fix, my this issue is resolved now.

Don't know if TP link has changed something from backend but i am not seeing this issue from the time i have applied the updated Firmware. You may want to inform to the concered team.
