Erratic sentence translation on 2 of 3 platforms

I‘ve waited a while to report this to make sure it wasn’t a fluke.
On web and Android, when using “sentence mode” the translate sentence button sometimes does nothing. It is seemingly random when it will and won’t work. Move on to the next sentence and all of a sudden it (probably) works again.
The part that confuses me the most is that this does not happen when I am using my iPad. So I am using the same Wifi connection, the same web service, everything. The only difference is whether I am working on Web (PC) Android app (Samsung S10) or iPad app.

Im in Africa, and the same thing is happening with my ‘sentence mode’ many things are not working. I did however see on the news that some cables were down near the UK, and a few other places, i suspect this is what the problem is. its the same on other websites for me
