"It must just be you then because I don't know anyone else had such a problem."
This seems like a rather generalist statement. It raises a few obvious questions, like exactly how many people do you know, who were on the SOR and who travelled to that country, without any problems, such as the PPU refusing a travel request? The fact that you don't know of anyone else, doesn't mean that such people do not exist, although that seems to be what you are implying, in your statement?
I've been told many different things, by many different people. A few weeks ago, my PPU told me that people on the SOR have problems getting into Spain. Yet, I know of one other person on the SOR, who travelled to Spain before the lockdown, and had no issues. So, people are free to talk about their own personal experiences of foreign travel and to express an opinion about what might happen, but when it comes to generalising about ALL people on the SOR, you need to provide some evidence.
