Some messages do not get decrypted in RiotX and say "Encrypted message"

HI. I have noticed that some of the messages do not get decrypted in RiotX. Sometimes when a user in an encrypted channel writes a message, It shows "Encrypted message" at the rooms tab (#), and when you press on that room it still shows "Encrypted message" where that message should be. I was able to fix that by going out the channel and coming back in, but now, since yesterday, my colleague send a 3 messages in encrypted room, first 2 i can see, the last one still shows "Encrypted message". I tried closing app, going out and in of the room, I even tried logging in via Riot Web and checking if I can see the message there - I it shows fine there, but RiotX just does not show that message.
I was not able to figure out a pattern of why that happens, but it seems to happen quite a lot in RiotX (which is some sort of a bug), at least for me. But first time I am not able to see that message after such a long time. It just does not refresh it and decrypt it.
Any ideas?

Thanks!
