Just a bit of maybe helpful information, not necessarily POD related but it may help someone so I'm passing it along, I was having a major problem with Canva, it just refused to work.
Over the past few years I had contracted Cataracts in both eyes so I have been using a 43 inch (1092 mm) television as my monitor. Cataracts have been corrected now but I got SO used to that screen with a ( Win 11 Recommended ) screen resolution set to 1600 x 900 that I simply left it that way. Canva doesn't like that at all, reduced resolution and Canva now works, just something to keep in mind if you happen to see anyone reporting Canva problems.
