Energel refill scratchy & thin?

0.7mm blue, writing thin lines & skipping. I thought maybe it got too cold last week when I had been outside for awhile, but it's continued even after warming up and being inside for several days. There is plenty of ink left in the refill. I use blue ink a lot, so kind of disappointed...any tips to rejuvenate it? I've tried scribbling a lot to get the ink flowing, and licking the tip (insert jokes here - give me your best shot!) like you would with a ballpoint, and it hasn't worked.

TIA!
