I started the discussion
to get help
(at 19:14), in the meantime I could work with delay and now I am back at home on my desktop (21:19).
And the error is not to be recalled, though I will remember for the future to restart next time. There are 23 applications started and only a few of them I know why I had launched them, on the other hand I should restart for networking. using this part since four years approximately and there where several updates on the iOS.
Obviousely no one but me has troubles with networking between Apple devices, is it so? Then all the reason is lying by me
Have a nice day/evening/morning, good by and thank you for help,
k.
