Storyline360 is very slow

I've noticed a huge lag in responsiveness while working in Storyline360. This started happening yesterday, July 4th, and is continuing today. Also, published images are rendering very blurry in both modern and classic players. 

Is anyone else experiencing the same problems? 

Nothing has changed in the configuration of my laptop, and Storyline360 used to run very smoothly up until July 4th. 

Any ideas on how this can be resolved would be great. 

Thank you,
