Suddenly, we are getting error messages when downloading caches in the area.

When downloading nearby caches, this error message almost always appears:
"Only chars 0123456789ABCDEFGHJMPQRTVWXYZ are supported.
Exception IllegalArgumentException
Send error report"
We are currently traveling in Scandinavia. We have two Samsung Android smartphones and use Locus Maps Classic (version 3.70.17). This worked flawlessly on both devices for years.
Suddenly, however, the aforementioned error message appears in most cases.
What could be causing this? If we can't download geocaches, the app is no longer suitable for geocaching. That would be a real shame! We have always been very happy with the app.

The same question 
Hi,
We are sorry for the inconvenience, but this error message is generated by the add-on Geocaching4Locus, not by Locus Classic. We are not the producers of the add-on, and we do not influence its functionality. The add-on has not been updated since April 2024, so we consider it not compatible any longer.
The only solution is to install Locus Map 4, in which the geocache search and download features are directly implemented into the app.
