I am running windows 10 ive tried spark 2.8.3, 2.8.0 and 2.5.8 with all im getting the same issue. Yesterday 2.5.8 worked fine no issue, nothing has changed and now its acting the same as the other versions. apparantly others can see my messages but i cant see theirs or mine. I know sparked worked on my Samsung tab pro which is a windows 10 devices but it wont work on my new laptop (ACER ASPIRE R). I use this client for work and nobody there can figure out why this is happening.
