I have the same problem. Time ago only with gifs. Now with images too.
This not only affects self destructing images. Normal images never seem to stop loading and you cannot even zoom to them since telegram seems to still be loading them (even though they are already done)
To this day it's still not back to normal
Why telegram didn't correct this bug after 3 days??? Are they asleep??!!
I have the same issue, tried rebooting and updating, didn't fix it. Started around the same time Premium started rolling
with version 8.8.3 you still have the problem that temporary media cannot be viewed because it is blurry.
I am using Nokia 7 plus, Android 10. That's OK to send self-destruct photo while other people can see it normally (Samsung with Android 8.0 or iPhone). But receiving temp photos kept blurry.
