I just had a live chat conversation with one of the guys at customer support. My problem remained.
I have a Sony alpha ILCE-6300. After going through initial struggle of installing the timelapse app on my newly bought camera 4 months ago, I had no problem with the app until today. I got an error message "Total number of content in this application has reached limit. Remove some content from this application. "
Restarting the camera didn't help, same with the app. I googled the problem and found this thread: https://community.sony.com/t5/PlayMemories/Help-with-error-total-number-of-content-in-this-application-has/m-p/588429. So I went ahead and reinstalled the app. That didn't fix the problem too.
I reached out to customer support and we did try a few things. The technician had an idea that it might be camera's cache problem. I reseted camera settings (which deleted all my presets...) and then installed the app over again. Didn't help. He asked me to take pictures in burst mode. That worked.
I would've just copied our conversation here but the technician turned on a survey I had to partake in and couldn't return to the conversation after...
Anyway, he gave me this link (https://www.sony.lt/pro/section/contact-support) which was supposed to be Lithuania Sony's customer support. Well, apparently there's no such thing.
I need a fix of sorts as soon as possible, thanks.
P.S. Memory card is a really good one and it seems to be working fine (burst mode test).
