The Union Bears have aimed a second banner display at the Rangers board.
The supporter group first held aloft a display suggesting club leaders had allowed standards to fall in recent seasons.
It read: "Everything from everyone?
"Fans gave all while you let our standards fall."
Then, not long before half time, the group unveiled a second display again aimed at the director's box.
It read: "Our loyalty is not a free pass for failure."

'Strange' Ibrox atmosphere as supporters argue over protests
There is a tense atmosphere at Ibrox with Rangers cruising to a 3-0 lead but very little noise in the stadium.
A protest has been planned by the Union Bears and Rangers Supporters Association with fans urged to join a walkout in the 55th minute of the match.
A statement read: "The Union Bears alongside the Rangers Supporters Association urge all fans to leave the stadium in the 55th minute during tomorrow's match - to send a statement to the board. Just as they gave up on Rangers after our 55th title, we will no longer tolerate their incompetence, excuses and disrespect.
"The board used our 55th title as free reign to coast on success, masking their lack of vision and leadership while dragging the club into mediocrity. These actions may seem drastic but they are necessary. The board has failed us too long and our loyalty will no longer be used as a pass for their failure.
"The Rangers support cannot stop until there is accountability, ambition and leadership worthy of our club."
