Two issues I noticed:
One due to WiFi not connecting to WPA Enterprise network, I had the cellphone reset. After reset I entered my Jolla account credentials.
After that I got notification for update. Except this is one update I had already applied. So Sailfish update may not be working well. Don't know.
Second issue is seen when using the Android app store. I tried to update the apps but the download keeps getting interrupted. Don't know again whether its network issue or store issue or something else.
