All my discord UI changed on my android phone

Yesterday evening, my discord UI has switched exactly to Iphone one, while I have an android phone, an huawei nova 5T, i am very confused and with lots of questions. I have features like to be able to ping off/on in my dms, which I didn't had, my notifications in app show a timer when they go off, which again I didn't had it, please help me cause I am very confused and hard to adapt to the new UI and in "What's new" it says its version is 137.11(null), I also never had the Dev only settings before.

I tried on my brother huawei p30 lite, and he has the version 126 stable, can anyone help me?
