spell check for more than 1 language in Android I try to make the spell check work for more than one language on my Android 8.1 Pixel 2 with Gboard. 

My question is NOT about auto correction or word predection.

The spell check is activated and the two languages (UK and German) are activated in Language preferences and Gboard preferences.

Changing the language while typing via space bar does not solve the problem. 

So far it is only working in Google Docs:






I read these stackoverflow answers, but it did not solve the problem:

I guess a solution for SwiftKey is even more difficult?

Thank you very much.
This is a known bug in Gboard:

I tested flesky and SwiftKey and they do at least a spell check for one language. 

Even if I only chose one system language and only one dedicated spell check language Gboard underlines nothing. In general this is the same for every App. Only Google Docs seems to have its own spell check.
