Thanks for taking the time to explain it to me. The Github issue also is very helpful. Seems that's exactly my answer to "Why do I need a fourth store in addition to F-Droid, AuroraStore and Obtanium" 😉
Have a nice day, thanks for the STT keyboard! I didn't really engage in the discussion because I'm exactly in the same situation as other people here. I already have the FUTO one and Sayboard... But eventually I'd like to replace FUTO software with free software alternatives. I don't like their licensing. So this is very welcome.
