It could be the ad-blocker causing the issue (as I use one in Firefox and Chrome but Edge is just vanilla as I never use it) but is certainly a bit of a weird "bug"
being prompted by email as well is normal. if you have completed verifly and have green ticks just ignore anything else - you don't need to do it again via MMB.
