Hi, 

Thanks for getting back to me.

I did all the things you mentioned, with a QB analyst on "Glance". I did incognito, I cleared cookies and history, and I have tried on Edge, Safari and Chrome. 

I have already exhausted my bank's technical resources too. 

As mentioned in my post, it must have something to do with how my QB accounts are setup:

Company A (personal QB account, but "unsubscribed"  because my accountant wanted  me to use her client QB subscription)...........had NO problem linking my BMO bank account to this one. Can click on RECAPTCHA

Company A (accountant subscription) Cannot link to my checking account due to invisible RECAPTCHA

Company B (accountant subscription) Cannot link to my checking account due to invisible RECAPTCHA
