Cesium app not working anymore

Hi,
I’m using /e/ on my Galaxy S7 for almost 2 years and it’s been great.
I just noticed something which apparently occur since the last update /e/OS 0.16
I use the cesium app (you can find it here https://cesium.app/fr/) which is an open source app community driven.
It used to work but it does not since the last update, which I find quite strange…
From what I read when I launch the app, it seems that it can’t connect to the internet, either in 4G or wifi.

Does someone use this app and have the same problem ?
Does someone have any idea of what could be done ?
Or is it something that we can’t do anything about and we have to wait for the next update ?

Thx for your help !
