My code - plaintext - is being double copied each time I write

Hello all!
It is the first time I am using a new device, a recent Huawei tablet to use FreeCodeCamp but all that I am writing is getting doubled. I am using the Browser that comes with the system, not Chrome or Firefox as recommended, all is being loaded, so I feel I have all set up with Java Script.
I am restarting my journey in the first part, New Responsive Web Design as I feel I forgot most stuff.
Also I am using a Public Internet Network.
What might be the problem?

Update: I am now using Chrome and even if less the problem persists.

Many thanks! xoxo

Welcome there,

If you are using a mobile device, the default keyboard does not always play well with the freeCodeCamp editor. I recommend you read the article on using a mobile device to view some tips - most importantly, check out the coding keyboards listed as they interface with the editor well.

Hope this helps

Thank you! <3 I guess I cant download the keyboard on the Huawei, but still thank you!
