Apart from the initial teething stages, when reCaptcha was first introduced, and which was a bit of a nightmare then, I have since had no trouble (using Microsoft Edge) - simply requiring a tick - until last week, when some one unleashed a tiger!
Now I am battling with from four to about a dozen pictures every time I want to post!
I tried several different browsers on my desk top computer, in recaptcha's early stages...but had identical results no matter which browser I used.
Norah tells me that Ash will look into this.
