Scan and keyboard input delay / MC version 15.6.1 / Agent version 15.3.0 / Android Enterprise Solved

Hi all, two of my customers are currently facing the same issue and we have two support tickets open for them, with no solution yet. Does someone of you having the same issue? Both customers are on MC version 15.6.1 with the most up to date device agent, version 15.3.0. They are using Android 10 and 11 Zebra devices with different models. They are enrolled as fully managed deivces, Android Enterprise. They use different browser applications for accessing telnet and web applications. On some devices, after 15 to 60 minutes, a scan and input delay starts and the delay gets longer and longer. Starting with a few seconds, up to more than 20 secsonds. After a restart of the device, the browser or the MC agent, it seems to be gone. But, after the 15 to 60 minutes it starts again and is getting longer and longer. We are not able to figure out which devices are affected. Some device with the exact same configurations / OS / LGU / model are affected, some are not. It seems that it is not an application side issue because it happens in different applications with different backends. The input is delayed, no matter if we are scanning or typing on the keyboard. If anyone has similar experiences, feel free to share your thoughts. If I get an answer on one of the tickets, I will update. Thank you Felix
