I regularly save my imaged on my PC via USB cable. For some months now I can’t find my screenshots. Earlier they were found in DCIM > Camera under the name “screenshot_date_number.png” but now there are only some from October. But there are newer ones on my phone!
I didn’t have the problem that nothing is shown, only the new screenshots. I tried it nevertheless a few hours ago. Sadly that didn’t help. Now even the file explorer of the PC loads for ages, what it didn’t do before.
