I have this annoying message since 2-3 weeks on all accounts. I tend to blame my (Opera) browser, but can’t be sure. If more people see this, I’ll file a ticket for it.
It looks like that it happens newly each 24 hours or so; something with Cookies. Ticking or unticking the checkbox does not help.
I recall that a similar 2-3 (4 ?) weeks ago, PRT installed a new installer. Maybe it is related.
The annoying part about it is mainly that the message comes 5-10 later than I clicked to start PRT (for IG the same as for IB) and that I usually grab a coffee while waiting for the platform to start up. Then I come back and nothing happened because the message needs to be clicked away. 🙁
