Cant connect arduino uno wifi rev 2(Mega 4809) to Blynk

@vshymanskyy would you take a look at this please?

The supported hardware list says:

Arduino UNO WiFi Rev.2 (use the example for MKR WiFi 1010)

but when you install support for the Arduino Uno Rev2 from Boards Manager…

and the latest WiFiNINA library the MKR1010 example from here won’t compile…

There are multiple compiler error messages like this:

It appears to be some issue with atoll not being defined as a public parameter in a certain combination of #if !defined() tests, but I can’t figure-out where the BLYNK_NO_LONGLONG and BLYNK_USE_INTERNAL_ATOLL values are coming from.
