We moved our 1000 Wyse 5070 units from 8.6 to 9.x sometime during spring time 2022.
Went through every 9.x release this year so far, at the moment 2208 with corresponding CWA package and BIOS version are in production with 2211 along with newest packages deployed for testing on about 60 clients. Looking good so far.
However, we still have issues with MS Teams (audio drops) or smart card readers not working (anymore).
Devices are used to connect to Citrix desktop environment throughout our logistics company by office workers of all kinds as well as shop floor personnel.
