Drawing arrows only sometimes works

I looked at other posts and couldn't find one with my issue, so I'm starting this topic to say that

I CANNOT DRAW ARROWS (SOMETIMES)

I enabled drawing arrows in my board settings, and I'm able to draw arrows 90% of the time. For some reason though, every now and then there are a few moments where I cannot draw specific arrows at a specific spot on a specific turn of the game. Sometimes, a perfectly working e4 to d5 arrow might work one turn, but not on the next. Sometimes an e4 to d5 arrow cannot be drawn but an e4 to d6 or whatever square works. Sometimes it's another random square instead of e4 to another non-d6 square. Is this a bug? Is it something wrong with my chrome browser?

Yes. It is sometimes difficult, especially with my device. It is not a bug.
