Activation weekend here over the weekend - 7 parks 300+ contacts on Dec Pre2 release.
callsign lookups work OK but there is a disturbing screen flicker introduced after the lookup process, another 2 screen OFFs and ONs occur every time a callsign entry is completed. It’s just in the brown lookup info panel above the callsign entry box.
[edit] I have QRZ and Callsign Notes Lookup options active. It’s faster and slightly less noticeable on the phone than my tablet. And when I enable HamQTH lookup in addition to QRZ an Callsign Notes, the flicker is longer and more pronounced.
I wouldn’t normally enable HamQTH if I have QRZ enabled under paid subscription but I wonder what the intention is for users. Should they be discouraged from enabling all lookup services? For the sake of performance?
Either that or perhaps hold off screen refresh until all lookups are complete.
