Telegram not working on A54

[lemonmeringue]

Hi there, please could someone help 

I've been trying for 2 days now to get Telegram to work on my phone. I make it to the first email verification, which works. 

Next the mobile text verification, which I never receive. I tried the call verification as well, I dont receive the call.

I have allowed all notifications for the app and I have cleared the cache. I deleted and re-installed multiple times. Nada.

 Is there something I'm missing? Tia
