Hi there @barakl.
Thanks for sharing your question with us! I can see that you also asked your question to our Support team and have found an answer so I’ll close the loop here for anyone else experiencing this issue.
Our engineering team is aware of these issues with preview text on iOS devices, and are working on a fix for these issues! However at this time we do not have a timeframe for when these fixes might be implemented.
For the time being, they've advised that as workaround - updating to the latest iOS version should resolve these issues, so if you have not done so already we would recommend making sure that your iOS device is on the most recent OS version and test again once you've updated if needed!
I’ll update the thread here when an solution has been officially implented.
