For me, it skips often on Android when playing hi-fi, whether I'm streaming, or have had it downloaded already. When set to high quality I have no problems.
At home on my Mac mini, I do not have a problem getting hifi. However, I do sometimes get the message saying there are streaming problems and I should switch to high quality. However this is not audible and it plays fine in hi-fi in spite of getting that message sometimes. I did have a lot of problems getting Amara SQ to work properly without skipping. I finally did get it to work, but only after updating to the newest version, and it only works on the installed app and not when using Chrome.
I got so angry with all the problems I almost gave up. However, I will say that now that it's working well, it really does sound great.
Good luck Antonio! I hope things work out for you, because if it does, it really is worthwhile.
