You can either use a different app instead, or you can disable the GZ compression in your profile settings on our website (not recommended).

Also Tivimate auto updates EPG only in the pro version.
At first start you might need to update EPG manually even in the pro version.

Tivimate also uses an internal cache, which can not be emptied and which gets stuck time to time. If your data is messed up there, you can not do anything, but ask for a different EPG url from us in a Ticket, which will refresh the EPG.
