Hi
I'm experiencing the same issue. Plugin version is 0.3.19 and using the web-based version of Windy on Chrome or Edge.

Same issue in the app, version 50.1.1.
I am on android.
The models ecmwf, gfs and icon have the problem very often.
iconEu and iconD2 work fine most of the time.
Does anybody have a solution?

Thanks,
Basz

@rittels :Thanks in advance! :) Can I buy you a coffee?
