I’ve been noticing the same, on and off. At first I thought it was my instance, but it’s fine on its own and through other UIs.
Aside from your thread, all else I could find was this issue, which is from May, long before I started noticing this, so not sure it’s the same problem
Version 2.37 temporarily broke compatibility with instances on Lemmy v0.19.3. Version 2.38.0 is already out with a fix.
