Sounds like no, but unless I go and mess with all settings on my phone it goes into sleep mode after 20 seconds for non-use or something like that. Then I have to either retype passcode or faceid to get back on, so it is easier for me to just get on a minute before, have my watch on the second hand, refresh every 10 seconds or so as not to lose my screen, and on the dot, click join. I found out by practicing at home that works best for me. I had my phone time out on me several times at home until someone mentioned refreshing. That method has worked better for me to actually get through.
