I think they are having shipping issues in general. I tried to order a couple of plugs recently and they came back with about 50 Euros and a minimum 90 days by sea to Australia. They did send me a nice E-mail explaining their shipping difficulties and that it was basically that or nothing. I figure 50 Euros for about 1.5 Euros worth of bits was a bit over the top, so I politely declined.
I have heard that because of a combination of Covid-19 issues, potential staff shortages, massive huge demands for many things, shortages of things, Brexit changes (specific to UK/Ireland) and other factors, such as too many shipping containers being in the wrong place and at the wrong time. That there are and have been problems.
Also all the flight changes, because of so many flights being stopped/cancelled due to Covid-19 travel restrictions, round the world, and many people being either put off or banned (in law), from traveling, in a number of cases (varies by country, obviously).
tl;dr
I can well believe it!
