Touch HD 3 missing audio/TTS functions (CIS)

Hello everyone. I'm new here, and to forums in general, so please forgive me if this question has been asked before. I tried using the search function but didn't seem to find much.

I bought my Pocketbook Touch HD 3 on the premise that it can play audio via bluetooth, as well as do TTS. It was written all over their website, and the shop assured it can do that, as did Youtube reviews.

However, my device doesn't seem to have any of these functions. TTS, Audio Player (and mp3 support to begin with) and bluetooth settings are all missing.
What's odd is that when I installed a TTS pack, it opened Voice Synthesis settings for me, but they're nowhere to be found otherwise.

I suspect it's a localisation issue.

Software version is: U632.5.19.832
Localization: CIS

Could it be that merely because I bought this device in Russia, it's missing all of these functions, even though I installed the software update from the US website?

Is there any way to restore full functionality to my PB632 device?

Please help. This device was an important gift to me and realising that it's stripped of its advertised functions is really underwhelming. Thank you.
