[Ubuntu-phone] Telegram notifications delayed on cellular data

[Anupam]

I noticed for last one week or so Telegram notifications arriving very 
late (by around 30 minutes to 1 hour) on 3G. On Wi-Fi it seems to work 
as before (it takes 2-4 minutes usually while in deep sleep, but this 
was present before). Anyone else seeing this?
I'm not really sure whether the problem is with my service provider. I 
don't face any significant slowness/connection drop etc. while browsing 
websites, on facebook etc.
My device is E5, OTA-12, stable channel.
With regards,
Anupam
