I was having a similar issue. GM wasn’t working with TiviMate on just one of my devices but my others subs were. Tried all of the regular maintenance then I backed up, uninstalled, reinstalled, restored and its back to normal.
I have all the same settings, except I had buffer at normal. I’ll up that and see what happens. Just weird that three services tend to have issues on tivi at times, but seem ok on other players - which is a bummer bc I love tivi.
generally no complaints about Gamers for the last few months though.
Not sure if this belongs here or in the Tivimate forum, but, my recent buffering and skipping issues seem to be because of Tivimate. Switching to XCIPTV gets a perfect stream while issues are occurring in Tivimate (premium).
